Favorable days for conception calendar. Calculation of a personal ovulation calendar

So, you are starting a new stage in life called - “ pregnancy planning».
📅 Ours will help you calculate the onset of ovulation and determine favorable days for conception. Indicate the first day of your last menstrual period and the length of your cycle in your calendar settings. If the cycle goes wrong, you can always edit the settings.

You should not relax and let such an important step take its course. And the point is not only in the physiological component of this term, but also in the fact that modern psychologists are increasingly saying that in families where parents worried about planning pregnancy in advance, children develop better both physically and emotionally.

Pregnancy planning is aimed at identifying and eliminating risk factors for future pregnancy and improving the health of both parents. Often, for a modern woman to be able to conceive, bear and give birth to a healthy child, serious preparation is necessary.

It includes an examination of the general and reproductive health of future parents and a set of measures aimed at ensuring optimal conditions for conception (providing optimal conditions for the maturation of the egg, its implantation (i.e., attachment to the uterus) and the early development of the embryo). Thus, these are measures aimed at eliminating certain risk factors, improving the health of future parents and creating favorable physiological conditions at the time of conception.

Planning a pregnancy

Pre-conception examinations

What do you need to do? Where to begin? Ideally, a woman should visit a gynecologist, dentist, therapist, ENT doctor and, if necessary, more specialized specialists in advance in order to identify and treat chronic diseases. In addition, she must take tests for “hidden” infections that occur unnoticed but can harm the child, examine hormonal status, do an ultrasound of the pelvic organs and undergo other necessary studies. In some cases, several months before a planned pregnancy, a woman is recommended to get vaccinated (most often against rubella and hepatitis B) in order to avoid problems during pregnancy. If there are hereditary diseases in the family (Down's disease, muscular dystrophy, Alzheimer's disease, Huntington's chorea, etc.) or cases of stillbirth, consultation with a geneticist is necessary. A geneticist can conduct special studies to identify genetic abnormalities and give a prognosis for the birth of a healthy child.

At the same time, you should not worry too much if the pregnancy is unplanned. In the first ten days, the embryo has not yet attached to the wall of the uterus and has not joined the mother’s blood circulation - therefore, those harmful substances that enter her blood (alcohol, drugs, etc.) do not reach the child. Immediately after establishing the fact of pregnancy, a woman should contact a gynecologist and undergo a full examination in order to identify and, if possible, eliminate health problems and prepare for the birth of a healthy baby.

If everything turns out to be in order, you can begin direct preparations for conception. It is recommended for a married couple not to take any medications for 2–3 months without consulting a gynecologist, not to smoke (as a last resort, reduce the number of cigarettes, switch to lighter cigarettes), not to drink alcoholic beverages (more than 100 ml of wine per day ), do not abuse coffee, eat more fruits and vegetables, do not take hot baths, do not go to baths and saunas, try not to get sick.

Women need to start taking vitamins three months before expected conception.

Conceiving a child

Now you can stop using protection and start actually conceiving. According to statistics, a healthy married couple who has sex 2-3 times a week without contraception usually takes several months to a year to conceive. So don't worry if it doesn't work out the first time. This may be due to recent use of hormonal birth control pills, stress, lifestyle changes, etc.

You can relax and just enjoy life and wait for the coveted lines to appear on the test, or you can take an active part, study your body, listen to it and thereby achieve your goal faster. It is worth noting that in some cases, especially with long and unsuccessful planning, it is simply necessary to know how your body works.

As you know, in order for pregnancy to occur, ovulation must occur in a woman’s body. Ovulation is the release of an egg from the ovary. Without the release of the egg and its subsequent fertilization, pregnancy is impossible.

Good to know

Ovulation occurs 12–16 days before the start of menstruation (for any cycle length). With a 28-day cycle, ovulation usually occurs in the middle of the cycle. If the cycle is shorter or longer, then the duration of the first phase - before ovulation - changes. After ovulation, it is always 12–16 days before menstruation (average 14 days). Pregnancy can occur if sexual intercourse occurs from 3-4 days before ovulation (sperm live 3-4 days) and ending a day after ovulation (egg lives about a day).

To more accurately determine ovulation, you will need to measure basal temperature and assess the condition of cervical mucus (the nature of vaginal mucus changes - its quantity increases, it becomes more viscous, viscous, glassy). Of course, all this cannot be classified as reliable signs of ovulation, but even as indirect signs they are quite important.

Infographics - Probability of conception

The statistical probability of conceiving a child in the first planning cycle is relatively small and amounts to 15–25%. About 50 percent become pregnant within the first 3 months of planning. 75 percent get the long-awaited pregnancy within 6 months of planning and 90% become pregnant within a year of planning. On average, a woman needs 4 months to get pregnant.

Good to know

If after a year pregnancy has not occurred, you should consult a gynecologist.

Interestingly, if you have sex more than 20 times a month, the likelihood of conception does not increase. There is a theory that with too frequent sexual intercourse in a man’s sperm, the number of sperm capable of fertilization decreases.

How does conception occur?

The primary follicle consists of an immature egg that is surrounded by a single layer of epithelial cells (follicular epithelium). Outside, the follicle is surrounded by a connective tissue membrane. Primordial follicles are formed in the prenatal period and in early childhood. By the period of puberty, out of 400,000–500,000 primary follicles, 35,000–40,000 remain, while the rest undergo reverse development. Of the remaining primary follicles, 450–500 fully mature, the rest undergo physiological atresia. The essence of physiological atresia is that the follicle begins to grow, but dies before reaching full development; the egg and surrounding epithelium disintegrate and are replaced by connective tissue.

In other words, every month in a woman's life, ovulation occurs, a total of 400 times during the entire fertile period. Under normal conditions, usually only one follicle matures, alternately in the right and then in the left ovary. Ovulation repeats more or less regularly every 28 days (lunar month). Not all follicles mature before fertilization. Most of them undergo reverse development - atresia. Follicle stimulating hormone (FSH) stimulates follicle growth to approximately 2 cm.

Ovulation itself is a dynamic process that occurs over a period of several minutes.

It occurs under the influence of the combined effects of gonadotropic hormones of the anterior pituitary gland and ovarian follicular hormone. Of particular importance is the increased synthesis and release of LH (preovulation LH peak). The rupture of the follicle is facilitated by the accumulation of follicular fluid and the thinning of the layer of ovarian tissue located above the protruding pole of the follicle.

Ovulation is the process of rupture of a mature follicle and the release of a mature egg from its cavity, ready for fertilization.

The egg, together with the follicular fluid, enters the abdominal cavity, and subsequently into the fallopian tube. Fertilization occurs in the cavity of the tube.

If this process is not carried out, the unfertilized egg quickly loses its vital functions (after 12–24 hours) and is destroyed.

Promotion of the egg in the fallopian (uterine) tube

The egg enters the fallopian tubes

A few hours before ovulation, the fallopian tubes receive information where exactly on the surface of the ovaries ovulation will take place. The funnel of the oviduct (fallopian tube) is prepared in order to “catch” the egg and prevent it from entering the abdominal cavity. The ciliated fallopian tube usually covers the place on the surface of the ovary where the vesicle should rupture. Thus, the egg almost immediately enters her cavity. The egg, having been released from the ovary and being captured by the oviduct, moves further along its lumen towards the uterine cavity.

However, sometimes, although very rarely, the egg during ovulation is not released from the follicular cavity, but remains in it; here its fertilization and further development can occur. In this case, a so-called ovarian pregnancy (graviditas ovarica) occurs.

In another extreme case, an egg that has fallen into the abdominal cavity but is not captured by the oviduct can be fertilized. In the abdominal cavity, the egg can implant in the peritoneum and develop there. In this case, we are talking about intra-abdominal pregnancy (graviditas abdominalis).

Much more often there are cases when an egg, normally fertilized in the oviduct, due to any changes in the physiological state of the mucous membrane of the oviduct or due to obstruction of its lumen due to pathological phenomena (inflammation), cannot move along the oviduct and is grafted directly into mucous membrane of the oviduct, where its development occurs. In this case, we are talking about tubal pregnancy (graviditas tubaria).

Good to know

The mobility of the fallopian tubes can be significantly reduced if a woman has previously suffered tubal inflammation. During the healing process, adhesions of the fallopian tubes form, which interfere with the movement of the egg through the tubes.

How does egg transport occur?

An egg released from the ovary under normal conditions enters the lumen of the fallopian tube and moves along the oviduct towards the uterus. One of the main factors determining this transportation is the wave-like movements of the oviduct, which occur in connection with contractions of the smooth muscles of its wall. After ovulation, these contractions become more intense. In addition, in all likelihood, an auxiliary factor in this case is the flickering of special cells - cilia, located on the surface of the epithelium of the mucous membrane of the oviduct, which promotes the flow of a special fluid in its lumen towards the uterine cavity.

In the cavity of the oviduct, in the expansion of the fallopian tube, fertilization of the egg occurs with sperm, which in huge quantities enter here from the vagina through the uterine cavity, and then move into the cavity of the oviduct both independently and thanks to the complex flow of a special fluid through the labyrinths of grooves formed by the folds of the mucous membrane of the oviduct .

During its movement through the lumen of the oviduct, the egg passes through the first stages of development, that is, crushing, so that a small embryo enters the uterine cavity, which attaches to the lining of the uterus and continues to develop here. The time required for transport of the fertilized egg and implantation occurs approximately on the 6th day after fertilization. This means that the egg moves through the fallopian tube within approximately 4–5 days.

Multiple pregnancy

Sometimes during fertilization two or more embryos are formed. This happens as follows. Or several eggs mature in the ovaries at once, which enter the tubes and then fertilization occurs with several sperm. Either the egg, after merging with the sperm, breaks up into two completely independent and viable cells. In them, so-called identical twins begin to be born and grow in parallel. The offspring born from one cell and one sperm in this case has an identical appearance, and in addition, the twins are endowed with almost the same set of chromosomes!

1. Dizygotic (twins) - are obtained from 2 fertilized eggs, so they can be very similar and completely different, of the same sex or different.


2. Identical (twins) - are obtained from one egg that splits after fertilization - they are absolutely identical to each other and, naturally, of the same sex.

Depending on when it splits, there are 4 options:

• If they separate quickly after fertilization, then each twin will have their own placenta and amniotic sac - this is the most favorable option (diamniotic, dichorionic twins - why this is called is clear from the definition).


• If they separate a little later, the twins will have a common placenta and different amniotic sacs (monochorionic, diamniotic twins).


• With an even later separation, the twins have both a common placenta and a common sac (monochorionic, monoamniotic twins).


• The latest division is Siamese twins.

Sperm migration

Since the egg is capable of fertilization only within 12–24 hours, in order not to die and be released with subsequent menstrual bleeding, it needs to meet with a sperm. During sexual intercourse, several tens of millions of sperm enter a woman’s vagina. A mature normal human sperm consists of a head, neck, body and tail, or flagellum, which ends in a thin terminal filament. The total length of the sperm is about 50–60 µm. It is much smaller than an egg. Sperm usually take several hours to reach the fallopian tubes; in general, sperm travel a distance of 15–18 cm.

Spermatozoa encounter various obstacles on their way. The cervix is ​​blocked by a plug of mucus, and even if they overcome this mucus, they can “get lost” in various “niches” and “dead ends” on the walls of the cervix. A large number of sperm have little mobility and viability and get tired quickly. A significant portion of them do not get further, but those millions that do break through soon collide with white blood cells. White blood cells are a powerful weapon in a woman's immune system, and they kill everything that is foreign to a woman's body - including male sperm.

Sperm fighting the cilia of the fallopian tubes

Once in the uterus, sperm begin their journey through the fallopian tubes towards the egg, which is quite difficult to do, because they move against the growth and movement of the cilia and against the rhythmic contraction of the tube. If by the time they appear there the egg is not yet in the tube, they remain free floating in a wide part of the fallopian tube and wait for it, sometimes up to several days.

Good to know

It has been proven that the lifespan of sperm in the female genital tract ranges from 24–36 hours to 8–14 days.

The likelihood of pregnancy increases if sexual intercourse coincides with ovulation, because then the cervical mucus becomes less viscous and the cervix softens. During ovulation, there is increased muscle activity in the fallopian tubes. Modern research suggests that this phenomenon promotes the movement of sperm, as well as the movement of the egg towards the uterus.

Good to know

Although orgasm usually speeds up the transfer of sperm, it is, of course, not a necessary condition, since there are many well-tested cases (both clinical and experimental) of pregnancy occurring in the absence of an orgasm in the female. In these cases, penetration into the uterus and passage through it of spermatozoa must depend mainly on the activity of the spermatozoa themselves

The first meeting of the egg and sperm - “undressing” the egg

By the time it meets the sperm, the egg is surrounded by a dense membrane, which is a nutrient medium for it. Some of the cells have already fulfilled their function and fallen off along the way in the fallopian tube. But most of these cells still protect the egg and prevent sperm from penetrating inside. Therefore, the sperm begins to actively try to penetrate inside. The upper part of its head (acrosome) produces substances - enzymes that dissolve the shell of the egg and help penetrate inside.

A team of strong sperm, remaining at this point in small numbers, actively attacks the shell of the egg, many die in this process. After some time, part of the shell becomes too thin and weak.

Penetration of sperm into the egg

The sperm that reaches the zona pellucida first is most likely to achieve fertilization. When one sperm has penetrated the egg, its surface membrane immediately thickens and becomes less permeable; at the same time, the remaining sperm lose their directed activity, and soon only single sperm remain in the vicinity of the fertilized egg. The sperm that remain outside the egg, where they have been so strictly prevented from entering, swarm around the egg for several more days and then eventually die. It is believed that these sperm create the necessary environment that helps the fertilized cell on its way through the fallopian tube.

Thus, after the penetration of the first sperm, the remaining sperm are not able to fertilize the egg. The mechanism that prevents more than one sperm from penetrating the egg is called the “polyspermy block.” In mammals, a block of polyspermy develops within a few minutes.

Now the genetic information of the egg and sperm merge, they become one, and represent a set of 46 chromosomes - a completely new combination of the ancestral heritage, which contains the blueprint for a new person. The fertilized egg is called a "zygote" and is about 0.15 millimeters in size.

After fertilization, the zygote begins to actively divide. Cell division occurs within 12–16 hours.

Migration of the egg to the uterus

For the first 3 days, the egg is in the fallopian tube and divides again and again.

Three days have passed.

During the process of fertilization, the egg, and subsequently the zygote, continues its movement along the fallopian tube towards the uterus. This is facilitated by contractions of the muscular layer of the tube and the movement of the cilia of its epithelium. After the formation of the zygote, the process of its division begins, which is called “fragmentation” (the division of the zygote received this name because the overall size of the embryo does not increase, and with each subsequent division the daughter cells become smaller and smaller). By day 5 of development, the cleavage embryo forms a blastocyst - a stage of development characteristic only of placental mammals. Now her task is to find the most optimal place in the uterine cavity for attachment and declare its presence to the woman’s body. A blastocyst is a “ball” of two types of cells:

• The external ones subsequently form a trophoblast, which provides nutrition to the embryo (trophoblast cells, after implantation with endometrial tissue cells, form the placenta).


• The internal ones form the body of the embryo.

The lower part of the cells will become the embryo, the upper part will become the placenta.

Implantation

In place of the former follicle (which burst during ovulation), the so-called corpus luteum is formed. It produces the hormones progesterone and estrogens. Thanks to progesterone, the lining of the uterus (endometrium) is well prepared to receive a fertilized egg.

However, the process of finding a suitable implant site often takes several days. As soon as the egg comes into contact with the wall of the uterus, attachment occurs. This location is usually the posterior upper wall of the uterus. After implantation, an intensive exchange of information begins between the blastocyst and the mother’s body. Hormones enter the mother's bloodstream, the detection of which allows pregnancy to be established. At the same time, the brain begins to actively produce hormones necessary for the development of pregnancy and stops the process of menstruation.

First signs of pregnancy

What you should pay attention to before taking a pregnancy test:

1. Sensitive breasts. Within a few days after conception, a pregnant woman may notice the first changes. Nipples become more sensitive than usual. This also applies to the rest of the chest. But sensitive breasts are not always a sign of pregnancy. Similar sensations may occur during ovulation or before menstruation.


2. Delayed menstruation. One of the main and most reliable signs indicating pregnancy, but not 100 percent. Perhaps you are reacting in this way to climate change, or it is a hormonal imbalance; delayed menstruation can be a sign of serious gynecological diseases. In any case, it is better to consult a doctor. However, a delay of up to five days is considered normal. It may also happen that you are pregnant, but your periods continue to come. Here we can only advise: after unprotected sexual intercourse, listen to your body and take a pregnancy test.


3. Frequent urination. It is one of the symptoms of pregnancy. But it can also be a symptom of illness, hypothermia, stress, etc.


4. Darkening of the nipple areola. This usually happens no earlier than two weeks later. However, darkening can be caused by the influence of sex hormones in a non-pregnant woman.


5. Increased salivation. As a rule, it appears with nausea in the first three months of pregnancy. Also, salivation is a characteristic symptom in almost all diseases of the oral cavity, gastrointestinal tract, and even inflammation of the trigeminal nerve.

A reliable result can be shown by a pregnancy test that reacts to human chorionic gonadotropin (), but the sensitivity of household tests can detect pregnancy only in the fifth week after the first day of the last menstruation (fifth obstetric week of pregnancy).

An ovulation calculator is one of the ways to determine the most favorable days for conceiving a child. After all, conceiving a child, even for a completely healthy couple, is not always easy; if you don’t “get” on a favorable day, then pregnancy will not occur. Some people are luckier and pregnancy occurs quickly, while others have to wait several months. Our ovulation and conception calculator will help you calculate that exact time.

But keep in mind that the results obtained may not be entirely reliable. The female body is very mysterious, and sometimes phenomena that are not entirely clear to medicine occur in it. For example, ovulation can occur towards the end of the menstrual cycle or vice versa in the first third (whereas it should be exactly in the middle). There are often stories on the Internet from women who claim that they became pregnant on days that were absolutely safe in terms of the likelihood of conception. So, an online ovulation calculator should not be considered as an independent means of contraception. It is useful as an additional remedy for some categories of women.

As you know, today the most effective and efficient means of contraception are combined hormonal pills and the Mirena spiral. But, unfortunately, hormonal contraceptives have many contraindications and side effects. And not all healthy women are recommended to take them... For example, if a woman has only one healthy sexual partner, but sex life is not regular - 1-2 times a month, or even less often, then you can use safer methods - spermicides, and on dangerous days, as a supplement, also condoms. Dangerous days can be determined by doing some calculations. You need to know the length of your menstrual cycle. Moreover, if it is irregular, then it is necessary to first calculate the average value, taking the last 6-12 months as a basis. Next, we calculate exactly the middle of the cycle. This way we get the approximate day of ovulation. We add a week before and a week after - the so-called dangerous time. Thus, half of the month is “dangerous” for a woman, and half is relatively “safe”. If you don’t want to count on paper and trust software calculations more, our ovulation calculator is at your service - you can calculate favorable and unfavorable days for conception right now by entering some data.

Now about something more pleasant - about planning a pregnancy using an online calendar. Here mistakes are no longer so scary, even if they happen. Using the program presented on this page, you can calculate the days most likely for pregnancy. It turns out there are already 9 of these days, or even more! But with frequent sexual intercourse, the number of viable sperm becomes smaller, which means the chances of conception are lower. Better to save your energy. Therefore, we not only use an online ovulation calculator, but also practice the good old method - measuring basal temperature. If financial possibilities allow, we buy tests to determine ovulation. The onset of ovulation is indicated by an increased (above 37 degrees) basal temperature (taking into account possible factors other than pregnancy that could give such a reaction) and a positive ovulation test. You can also confirm the release of an egg from the ovary using an ultrasound examination. There are also subjective signs, such as increased sexual desire, pain in the lower abdomen or from the ovary and fallopian tube involved in the process, the appearance of transparent, rather profuse vaginal discharge.

If you only had part of the evidence of ovulation, but conception did not occur, do not worry. According to statistics, a very small number of couples succeed in getting pregnant in the first 1-3 months of trying. And doctors generally say that you need to start worrying if pregnancy does not occur for more than 10-12 months of sexual activity without contraception. The fact is that that most favorable day does not happen every menstrual cycle - so, calculating an ovulation calculator is only half the battle. To achieve quick results, psychologists recommend simply relaxing and stopping counting and calculating things, making love in certain positions and according to the clock, etc. Stress has too negative an effect on our body. So if you're in a rush to become parents, just go on vacation and enjoy each other's company! And the printed ovulation and conception calculator will then become for you one of the pleasant reminders associated with the period of planning a baby.

If a woman has realized that she is ready for motherhood, and at a family council with her husband it was decided that it is time to have a baby, couples often wonder when is the best time to conceive a child. There are many methods that help determine which days are favorable for conception: calendar and vaginal, test or ultrasound, traditional methods or a special calculator. A fairly common method is the child’s conception calendar, which will have to be kept for about three months.

When is the best time to conceive a baby?

Every parent wants their future baby to be healthy and smart, so spouses often plan in advance, choosing the best time to conceive a child. Moreover, often this is not just a favorable period for conception, but also a complex of other factors. A responsible approach to the issue of pregnancy is necessary. Sometimes even the best time of year matters.

Attention! Scientists have proven that mothers who give birth to their first baby before the age of 22 have a minimal risk of developing breast cancer.

Experts consider the optimal age for women to conceive a child to be 20-26 years old. This is the most suitable period for the birth of your first baby, because the first birth at the age of 30 can be complicated by unforeseen deviations. And at the age of 20, it is much easier for the body to recover after childbirth; the duration of the postpartum period at this age is shorter and it proceeds much easier.

Regarding the season when it is best to conceive a child, there are no generally accepted standards. Each season has its own disadvantages and advantages, so the choice of which month is best to conceive a child remains with future parents. If fertilization occurs in the summer, then the birth will occur in the spring months, when the woman experiences vitamin deficiency and cold attacks, and the last months of pregnancy, when the body is most enlarged, will occur during the period of frost. Therefore, the calculation should be made taking into account that you will need warm clothes of a larger size, because it is necessary for a pregnant woman to walk in the fresh air. And when walking, you will have to take into account the presence of ice, which is dangerous if you fall. Therefore, these months are not the most favorable time for the last trimester.

If the date of conception of the child is calculated in the fall, then the birth will occur in the summer months. The disadvantage of such a pregnancy is the tense first months, when the mother needs to protect herself from colds and taking medications that negatively affect fetal development. But there is a certain advantage to such a pregnancy: the baby will be born in the summer, so you won’t have to wrap your baby in a bunch of clothes and constantly worry about how well he is dressed.

How does the process of conception occur?

In order to correctly calculate the best days to conceive a child, it is worth familiarizing yourself in more detail with the process of conception - how it happens, phases, etc. Conventionally, experts divide the process of conception into several cycles: ovulation, fertilization and transportation of the fertilized egg to the uterine cavity for consolidation. For ovulation to occur, a mature egg is required. In order for it to mature successfully, it needs the influence of FSH, and for its successful release, luteinizing hormone is needed.

With normal hormonal status, in the middle of the cycle, a mature female cell leaves the ovary, i.e., the ovulatory process occurs, after which, as a rule, the cell is sent to the uterine cavity. The whole process takes several hours, therefore, in order to catch the moment favorable for pregnancy, it is necessary that the sperm is already in the uterus or tube when the egg moves through it. After the release of seminal fluid, sperm can live in the uterus and tubes for another 2-3 days. It turns out that every month when a woman ovulates, the most favorable days for conceiving a child occur. The duration of these favorable days is about 72 hours.

So, the period of ovulation has passed and the sperm has met the cell. But in order to become pregnant, sperm must penetrate the cell membrane. A group of sperm dissolves this membrane and only one penetrates inside, after which the sperm unites with the cell and a zygote is formed, which begins to rapidly divide into many cells, uniting into a cavity with liquid and an embryo inside. All these processes take place while the cell is implanted into the uterine cavity, in order to then gain a foothold in it. Usually implantation occurs on days 20-22 of the cycle. After consolidation, we can assume that conception has occurred.

How to determine the optimal date of conception

Sexual intercourse performed just before the start of the ovulatory process is favorable for conceiving a child, so that the sperm have enough time to reach the cell. If you correctly calculate the date of conception, then pregnancy will definitely happen. If you accurately calculate at what time the cell is released and actively engage in sexual intercourse on these days, then the chances of pregnancy will be maximum. How to determine favorable days for conception?

How to correctly calculate the optimal day for conception? It is necessary to accurately determine the ovulatory period. Since the cell lives only half a day, sexual intimacy a day or two before ovulation is more preferable than after it. After all, sperm need some time to get to the right place. The best way to calculate the day of ovulation, according to most women, is based on measurements in the basal temperature chart and special ovulation tests. In order to accurately calculate the period of conception, a woman is recommended to keep a basal schedule for at least three cycles, determining the exact days of ovulation. Using the data obtained, you can create a calendar for conceiving a child and calculate the optimal days for this.

Conception calendar - what is it?

You can create a calendar yourself or use an online application, which also quite accurately allows you to identify dangerous days for women who do not want to get pregnant or favorable days for those especially expecting a baby. To roughly imagine the work of such a program, which carries out calculations, determining days that are safe for conception, the time of ovulation and the best days for pregnancy, let’s take a look at the factors on the basis of which it was created.

For almost all women, ovulatory processes occur approximately in the middle of the cycle. The online program makes calculations, identifying the middle of the cycle, and based on the calculated result, it determines favorable and dangerous days for pregnancy. The program also takes into account that fertilization cannot occur at the end of the cycle and during menstruation. These days are considered safe. Such calculators help determine on what days the next ovulation will occur, menstruation will begin, etc.

To calculate the time of release of a mature cell using the conception calendar, you simply need to enter data about the last menstruation and the duration of the cycle. The calculator will give results based on the date of conception, ovulation, when a woman has a good chance of pregnancy, and when having sex will not lead to conception. It cannot be argued that the results provided are impeccably accurate, but they allow us to roughly determine dangerous and safe days for fertilization. Conceiving a child according to the calendar can be calculated a year in advance, then it will be easier for a woman to navigate when to plan protected or unprotected sexual relations, depending on the ultimate goal. Such calendars are quite easy to use; they often have certain days colored in the right colors, which makes working with the program much easier. Using calendar data, you don’t have to look for how to calculate the date of ovulation or conception.

Is it possible to calculate the gender of the baby?

Different parents have different approaches to pregnancy planning, some are glad that the long-awaited conception happened at all, but for others it is important what gender the children born will be. The conception calendar can even calculate the days when the time is most favorable for conceiving a daughter or son. Such calculations have a completely logical explanation.

• Sperm containing a male chromosome set are distinguished by their nimble nature, they move faster and are more active. But such sperm live much shorter than “tadpoles” with a female chromosome set.
• If sexual intimacy takes place during the ovulatory period (with a 28-day cycle, approximately 14 days before the expected start of subsequent menstruation), then the spouses increase the likelihood of conceiving a boy. If a couple really wants to give birth to a girl, then it is recommended to have sexual contact a couple of days earlier.

But such a rule, unfortunately, does not always work. The fact is that today it is very difficult to find absolutely healthy people; each of the future parents has some kind of health disorder, including reproductive health. All this affects the speed of spermatozoa. If a partner has an acid-base imbalance in organic structures, in particular in the reproductive system, or her cervical and vaginal secretions, under the influence of pathological factors, have changed their composition to be more aggressive for sperm, then their motor activity may seriously decrease. Also, the “live men” lose their rate of fire if the man is in a state of severe physical fatigue.

So, the time favorable for the desired pregnancy has been determined, the spouses are ready, everything seems to have been done correctly, but conception still did not occur. To increase the chances of successful fertilization, it is recommended to follow some tips.

Men should avoid hot baths, steam rooms and saunas, because excessive heat can have a detrimental effect on sperm and simply destroy them. Also, it is better for future fathers to avoid horseback riding and cycling, which is associated with the negative impact of constant friction of the scrotum on sperm. Taking various kinds of steroid drugs, various stimulants for building muscle mass and other pills that bodybuilders are addicted to today is strictly prohibited. You will have to stop taking them at least six months before the planned conception.

There are also restrictions for women. It is better to give up various paraphernalia for sex, such as stimulating lubricants and creams, because such products often change the vaginal environment, which leads to the death of sperm. Any douching can have a similar effect, so it is also better to avoid them while trying to conceive. The position also matters, for example, in the missionary position, sperm loss will be minimal, but penetration into the vagina, on the contrary, will be maximum. And to consolidate the effect, it is better for your partner to lie on her stomach for a while after sex.

As you can see, the favorable time for conception depends on many factors that must be taken into account. Therefore, planning a pregnancy requires the most serious and responsible approach, then you will get exactly the results you have been waiting for so long.

The birth of a child is the most joyful and happiest moment in the life of every person. Many of us prepare for this day in advance, just as we prepare for the moment of conceiving a baby. Naturally, it is impossible to accurately determine the day when conception will occur; to a large extent, everything depends on chance and the sexual compatibility of the partners. But any of us can influence the fact that this day comes sooner or later. In addition, we can plan the conception of a child using the most accurate calendar. To do this, you don’t need much, you just need to follow the recommendations, know the peculiarities of physiology and firmly believe in miracles.

Many expectant mothers begin to panic when, within 2-3 months after giving up contraception, they do not see the coveted two stripes.

Conception as a physiological process

In order for a small person to be born - a boy or a girl, there must be a meeting of two cells: the female - the egg, and the male - the sperm. After their fusion, a fertilized egg is formed - a zygote. Every month, a small bubble, a follicle, containing an egg, matures in a woman’s body. The walls of the follicle, under the influence of estrogens, increase to the size of a cherry and burst in the middle of the menstrual cycle, releasing the egg. This process is called ovulation. The egg retains its ability to fertilize for 24 hours, so it is important to plan the conception of a girl or boy within this period.

Sperm are produced in the male reproductive organs – the testicles. They are formed during a certain cycle, the average duration of which is 70-75 days. Before reaching their goal - the egg, sperm have to travel a long distance through the uterus and fallopian tubes. They cover this distance in an average of 2 hours, and retain the ability to fertilize for 2-7 days. During the first 12 hours after the meeting of the male and female eggs, fertilization usually occurs, followed by the formation of a one-cell embryo.

How to plan the gender of your future baby?

Almost every girl, and ultimately a future mother, even before finding out that she will soon have a child, firmly knows who she would like to give birth to - a girl or a boy. Today there are many methods for planning the gender of the unborn child, both at home and at the medical level. Expectant mothers sometimes resort to the most unexpected methods, in the hope that they will help achieve the desired result and determine who will be born. Since ancient times, our mothers and grandmothers relied only on chance, and until recently they did not know who was in their tummy. However, modern progress, the development of astrology, fortune telling and predictions, has prevailed over natural processes. On the Internet there are a lot of different recommendations for planning the conception of a child of a certain gender. For this, the phases of the moon, the days of the week, the season of the year, special positions during sexual intercourse, properly arranged furniture, special diets and diets, as well as all kinds of calendars that promise to accurately plan the gender of the unborn child are used.

Initially, it is important to approach the process of conception itself. To make its probability as high as possible, many women use a special calendar, which is based on accurate readings of the menstrual cycle. Thus, having all the necessary data at hand, calculating the exact ovulation period down to minutes is quite simple. All that remains is to act and hope for a positive result. Using a calendar to conceive a child, you can just as easily calculate the most dangerous and safe days. Fertilization can occur both on the day of menstruation and after it. Even if you do not use a calendar to plan conception, checking this data in practice is quite simple. The main signs that the moment of ovulation has arrived:

• intimate discharge noticeably increases in volume;
• sexual desire increases;
• basal temperature changes;
• short-term aching pain appears in the lower abdomen.

Each woman can calculate an exact individual plan for conceiving a child either independently, guided by calendars, personal records, or on the Internet, using special calculation services. It is also worth noting that productive ovulation in women does not occur in every menstrual cycle - this is a feature of the female body.

Ponytails, braids, dresses - who doesn't want a little princess? Before planning a conception, many married couples initially dream of a future girl. And this desire is quite understandable. It is generally accepted that a child is happiness from God, and it does not matter who it is - a boy or a girl. However, the irresistible desire to have a daughter sometimes takes precedence over natural processes and the hope of “maybe.” On numerous women's forums, expectant mothers are happy to share the secrets of techniques on how they managed to plan future happiness in the form of the birth of a girl. There is an opinion that the most accurate calendar for conceiving a girl is the Chinese one. Its specificity is based on a combination of the age of the expectant mother and the month the child was conceived. Either it’s a matter of chance, or the calendar really works, but if you adhere to its conditions, babies are really born. The Chinese table is also very popular in its use for conceiving and giving birth to a girl. It is based on the orientation of the date of birth of the spouses to the month when conception occurs. By following special recommendations and carefully calculating your data using calendars, you can hope that in 9 months you will become the mother of the most beautiful girl in the world.

The birth of a boy is no less anticipated than that of girls. And although raising a real man is not an easy task, having a son is a pleasant responsibility. As with the calendar for planning the conception of a girl, the principle of operation of the Chinese and Japanese calendars is based on the same parameters. The summary table shows the birth dates of the expectant mother and father, as well as the month and day of ovulation. Everything is simple and transparent - at the intersection of data you can see a certain indicator that shows the probability of having a boy, to one degree or another.

Conclusion

It is generally accepted that the birth of a child is a gift from God, and it is impossible to plan this event. But in the conditions of modern life, when planning not only the birth of a baby, but also its gender is a very common thing, more and more married couples are resorting to various similar methods, because wanting a specific son or daughter is a completely normal desire of every person. Be that as it may, the main thing is that the baby is born healthy, to the joy of mom and dad.

Calculate ovulation using an online calculator

Above on the page there is a calculator that will allow you to calculate ovulation online. The service will give you the opportunity to see a calendar for the next three months, in which the dates most favorable for conceiving a child will be marked. You will need to enter the required information:

1. Date of the first day of the last menstruation;
2. Number of days of the menstrual cycle;
3. Duration of bleeding, that is, how many days menstruation lasts.

• Red – days of menstruation;
• Yellow – days of ovulation with the indicated percentage probability of conceiving a baby;
• Green – the day of ovulation with the maximum potential for fertilization of the egg;

Thus, the program allows young spouses planning to replenish their family to calculate ovulation to conceive a long-awaited baby.

An additional option of our service, which calculates ovulation for conception, is special marking of days favorable for conceiving a girl and days with a high probability of conceiving a boy.

These day categories are marked with corresponding icons.

Gynecologists call days favorable for egg fertilization fertile. Women who decide to calculate the ovulation calendar in our calculator will receive fairly accurate and reliable data on fertile days in their body.

How does ovulation occur?

Ovulation is the maturation of an egg in the female body within the biological cycle of the reproductive system. The maturation of an egg is its readiness for fertilization by a sperm and, as a result, the birth of a new life inside the expectant mother.

Normally, in a woman’s body, the menstrual period lasts from 28 to 35 days. The starting point of this cycle is the first day of menstruation. The finishing point is the first day of the next menstruation. Usually ovulation occurs exactly in the middle of this cycle. If the menstrual cycle is 28 days, then on the 14th day. However, seven days are considered fertile (or favorable for conception): 1-2 days before ovulation, ovulation itself, 1-2 days after it.

If fertilization does not occur during this period, the mature egg simply dies.

Luteal phase (corpus luteum phase)

1. The menstrual cycle usually repeats every twenty-eight days. On its first day, the woman notices spotting and spotting from the vagina. This cycle is a normal physiological process created by nature in order for a woman to become pregnant, bear and give birth to a baby.
2. Gynecologists distinguish three phases in the menstrual cycle:
3. Follicular phase;

When your period arrives, the follicular phase begins. The uterus rejects the layer of mucous prepared to receive a fertilized egg, and the maturation of a new follicle begins in the ovary. During this period, the hormones progesterone and estrogen decrease in the body. However, there is more hormone that stimulates follicle growth. This phase lasts approximately thirteen days.

Then comes the ovulatory phase, which lasts only forty-eight hours. This period ends with the release of an egg, which can be fertilized by a sperm. At the moment, fertility is at its maximum.

The time comes for the luteal phase, or the corpus luteum phase, which will last about two weeks.

This phase can progress to pregnancy if the egg was successfully fertilized at the previous stage.

In the luteal phase, the corpus luteum is formed from the ruptured follicle, which is the cells that generate progesterone, a necessary hormone for the onset of pregnancy. During this period, the basal temperature increases, which will maintain the corresponding indicators until the start of the next menstrual cycle, if pregnancy has not begun. The corpus luteum is the main endocrine element of the ovary. Because without progesterone, gestation is impossible.

The pituitary gland in a woman's brain produces luteinizing hormone. It promotes the formation of granulosa cells in the ovarian follicle, which produce progesterone. The corpus luteum in a woman’s body is a temporary gland that exists only in the luteal phase of the menstrual cycle. In the first three days of the corpus luteum phase, granulosa cells in the follicle cavity actively increase in size, and capillaries appear between them. Each cell of the corpus luteum is saturated with blood vessels. The corpus luteum has the most active blood flow in the body during this period. Three to four days after the ovulatory phase, the generation of this unique blood supply system - a network of vessels in the corpus luteum - is completed. At this moment, progesterone is most actively produced in the woman’s body. If fertilization of the egg does not occur, the generation of progesterone, the main function of the corpus luteum, ends on the twelfth day after ovulation. The corpus luteum in this case is an endocrine gland measuring 1-1.5 cm, which is now entering the stage of reverse development.

Ways to calculate the ovulation calendar

Calendar calculation method

Each female body has its own individual calendar of days with maximum fertility, that is, days most favorable for sexual intercourse, which can result in fertilization of an egg by sperm. There is a calendar method for calculating ovulation - favorable days for conception. It is based on the characteristics of the menstrual cycle in a particular woman. It is not difficult to calculate it if the cycle is regular. For example, a girl knows for sure that her menstrual cycle is 30 days. In this case, thirty must be divided in half and subtracted two days. That is, 15 minus 2. Thus, on the thirteenth day after the first day of the last menstruation, a favorable period for conception begins. In our example, ovulation will be on the fifteenth day, and fertile days begin on the thirteenth day of the cycle.

But this is only possible with a regular cycle that does not go astray. Such calculations will be inaccurate and ineffective during the menstrual cycle, which for a woman either increases or decreases throughout the year.

Ovulation test

Another way to calculate the day of ovulation is to purchase an ovulation test at the pharmacy.

The pharmaceutical market has a rich range of such tests. Just like a pregnancy test, an ovulation test should be immersed in a container of urine and wait for two lines to appear.

If in a pharmacy pregnancy test the markers of two strips are focused on the presence of the hormone human chorionic gonadotropin (hCG) in the urine, then in the ovulation test markers of luteinizing hormone (LH) are used. If you have irregular periods, it is not easy to determine the exact date of ovulation using this method.

1. Calculation of ovulation based on physiological characteristics
2. In addition to all of the above methods for calculating fertile days, there is a method that any girl can use independently (without the help of a specialist). You just need to carefully observe your own body and trust Mother Nature.
3. The nature of vaginal discharge;
4. Soreness of the mammary glands;
5. Increased libido (sexual attraction to a partner);
6. Emotional irritability;

Discomfort in the lower abdomen;

In different phases of the cycle, which we talked about above, the expectant mother experiences different discharge. A day or two before the ovular phase, vaginal discharge is usually clear, liquid (possibly viscous), and has a viscosity similar to egg white. In some cases, brown, bloody discharge is also possible during this period, popularly called “smear.” And in the follicular phase, vaginal discharge is of a different nature - creamy, sticky, or there is no discharge at all.

Sometimes a girl’s breasts swell a day or two before ovulation, and touching the nipples becomes painful. This occurs due to an increase in the level of progesterone in a woman’s body, that is, hormonal changes.

The increase in sexual attraction to the future father is due to nature itself, which makes it clear to the female body that now is the best time to conceive and then bear a child.

A dominant follicle matures in one of the ovaries (left or right). This process on the day of ovulation may be accompanied by nagging (as during menstruation) pain in the lower abdomen.

Basal temperature

If your menstrual cycle is irregular, the most accurate picture of your fertile days on the calendar will be obtained by regularly measuring your basal temperature.

Within the phases of the menstrual cycle described above (follicular, ovulatory, luteal), in most cases, a woman has different basal temperature readings. This is explained by a change in the dominant hormones in the body of the expectant mother. During the follicular phase, basal temperature is usually low. In the ovulatory phase, basal temperature rises to values ​​from thirty-seven to thirty-seven and three tenths degrees. And it is in the corresponding range of values ​​until the new follicular phase.

In order for the method of measuring basal temperature to identify the most favorable days for conception to be effective, a woman should follow a number of recommendations:

1. Measurements are taken rectally or vaginally for at least five minutes in a quiet lying position;
2. It is better if the thermometer is mercury rather than electronic (the same for the entire measurement period);
3. Measurements should be taken in the morning at the same hour, without leaving bed, after a long night's sleep (lasting at least six hours);
4. Measurements must be taken for at least two months, recording the result every day.

The site has a very convenient service that allows the expectant mother to enter basal temperature values ​​into the program every day, which, after entering information daily over the woman’s two menstrual cycles, will accurately and clearly calculate the days of ovulation online.

Taking tests in the laboratory

Different methods for determining fertile days have varying degrees of accuracy, because each female body is unique. Let us remind you that calculating ovulation online in our calculator is one of the highly accurate and effective methods.

There is another method for calculating ovulation days for a long-awaited pregnancy, which we will now talk about. At different stages of a woman’s menstrual cycle, the content of one or another hormone changes in her body.

In a modern laboratory (where everything is sterile and precise, like in a pharmacy), a girl who wants to get pregnant can get tested for the main female hormones.

1. Follicle-stimulating hormone (FSH) increases on days 3-5 of the menstrual cycle;
2. Luteinizing hormone (LH) – on days 3-8 or 21-23;
3. Prolactin – on days 3-5 or 19-21;
4. Estradiol – on days 4-7 and 6-10;
5. Progesterone - on the 6-8th day.

The increased concentration of these hormones in the body, detected during laboratory tests, indicates to the gynecologist which phase or day of the cycle is currently taking place. This allows you to accurately predict the day of ovulation and fertile days.

In addition, taking tests to the laboratory will help identify a possible disease in the expectant mother and treat it in a timely manner.
