How to correctly calculate the day of conception of a child. How to find out before a delay whether conception occurred immediately after ovulation

Sooner or later, every young family faces the issue of having children. Some people succeed right away without prior pregnancy planning, while others have to do a lot for this. But it all starts small. Each woman herself can calculate and determine the most favorable days for conceiving a child. In this article we will talk about how to do it correctly.

Favorable days for conceiving a child: menstrual cycle and ovulation

Each woman's menstrual cycle is individual. Normally, it can last from 28 to 35 days, be regular, without any disturbances that may occur against the background of diseases of the genitourinary system or severe nervous stress.

Each menstrual cycle is divided into three main phases:

Follicular phase - begins with the day of slight bleeding from the uterus through the vagina. It lasts 14 days for women whose menstrual cycle is 28 days, and about 17 days for those whose cycle is 35 days. During this period, a follicle matures in one of the ovaries and contains an egg.
The ovulatory phase begins on the 14th (17th) day of the cycle and lasts only 16-32 hours. On this day, the level of luteinizing hormone in a woman’s blood increases significantly, which stimulates the release of the egg from the follicle. This process is called ovulation.
Luteal phase - begins on the 17th (20th day) of the menstrual cycle and ends with the beginning of the follicular phase, that is, it lasts approximately two weeks. During this phase, a woman's uterus prepares for either the next cycle or the implantation of a fertilized egg.

Consequently, a woman can become pregnant only during the ovulatory phase - three days before ovulation, on the day of ovulation and the day after it. The main thing is to identify it in a timely manner. This can be done in several ways.

Methods for determining ovulation

There are many different methods, both scientific and folk, by which you can determine the best days for conception after menstruation. Each of them is effective in its own way, but cannot provide a 100% guarantee that fertilization will definitely occur. After all, the process of conceiving a child depends on many factors - the health status of the couple who wants to get pregnant, their lifestyle, and the activity of male sperm. If everything is in order with these indicators, then the probability of conceiving a child on the day of ovulation is 37%. After all, you also need to take into account the fact that ovulation does not occur every menstrual cycle. Doctors say that only 8 out of 12 months of the year women enter the ovulatory phase.

Now let's look at each method in order to calculate the best days of the cycle for conception.

The best days to conceive according to the ovulation calendar

To do this, a woman will have to sacrifice 3-4 months, during which she needs to carefully examine her menstrual cycle. In order not to miss a single important moment and to figure out which days are most favorable for conceiving a child, you need to get a notebook or notebook where a woman will mark the phases of her cycle.

This is necessary in order to determine the regularity of your periods. It is extremely important that they begin and end systematically at equal intervals. Once you know the exact number of days in your menstrual cycle, it will be easy for you to calculate the day of ovulation. How this is done: the number of days in the cycle is divided by 2, since ovulation always occurs in the middle of the cycle. If your period cycle is 28 days, then you need 28:2. As a result, it turns out that the 14th day of the cycle is the most favorable for conceiving a baby. But this indicator may not be accurate. To make sure that ovulation has occurred, you can use the following methods:

On the day marked on the calendar, conduct a special test, which is sold in every pharmacy. The principle of its operation is the same as that of any pregnancy test: if, after urinating on it, it shows you two stripes, it means that ovulation has occurred or is approaching.
Measure your basal temperature over several menstrual cycles. This is done daily in the morning, without getting out of bed, rectally. The closer it is to ovulation, the higher the temperature will be; directly on the day the egg leaves the ovary, the temperature will drop sharply, and then rise again.
Observe the physiological changes that occur to you. They say that your body can tell you about the most favorable days for conception. When you feel a particularly strong sexual desire, and at the same time the nature of the cervical discharge from the vagina changes - it becomes transparent and viscous - this means that the probability of becoming pregnant is very high.

Knowing the day of ovulation, you can create a calendar for conceiving a child. To do this, print out a calendar, paste it into your notebook and mark the day of ovulation in red, and in another color, for example green, mark the remaining favorable days for conception. By the way, there are many sites on the Internet where you can create an ovulation calendar online. In addition, this kind of application can be downloaded to your phone or any other electronic gadget. In addition to everything, they have a special function. They are like an alarm clock, signaling the onset of ovulation so that you don’t miss it in your everyday bustle.

Best days to conceive according to ultrasound

If the first method of calculating the best days to conceive a child does not inspire confidence in you, then contact specialists who, using a vaginal ultrasound examination, will tell you the exact date of your ovulation. However, in this case there are also certain recommendations that should be followed:

Your trip to the ultrasound should occur no earlier than a week after the end of bleeding from the vagina. At this time, follicles are already beginning to mature in the ovaries, the number of which and the time of their rupture can be determined by a diagnostician.
An ultrasound will need to be performed every two days after the first visit throughout the entire menstrual cycle, so as not to miss the day of ovulation.
After ovulation, a specialist will monitor the processes occurring in your uterus. It is important that the endometrium, to which the fertilized egg will be attached if conception occurs, develops. Indeed, for this reason, conception may not occur.

Ultrasound is the most accurate way to determine the best days to conceive. With its help, you can even calculate the gender of the unborn child. To conceive a boy, sexual intercourse must take place on the day of ovulation, and for several days before it. This theory is based on the characteristics of the X and Y chromosomes. The female X chromosome is less active, but more viable, and the male Y chromosome is extremely active, so it can reach the egg very quickly. Of course, if it is fundamentally important for future parents who will be born to them, then it is better for them to immediately contact some reproductive center, where geneticists can select the necessary sperm and artificially fertilize your egg with them.

Conceiving a child according to the lunar calendar

Astrologers claim that a young couple can become pregnant not only on a favorable day for this in the woman’s menstrual cycle, since there are special lunar days for conceiving a child. At the same time, scientists claim that it is even possible to determine the gender of the unborn baby using the lunar calendar of the days of the child’s conception. Whether to believe this method or not is a personal matter for everyone. If you find this option interesting and reliable, then you can try to use it, especially since we have already prepared a year for you.

If you decide to become parents in the near future, then you need to radically take care of your lifestyle and health, as these are important factors in the process of conceiving a child. Let's consider a number of general simple recommendations for both women and men:

Before planning a pregnancy, completely, which kills eggs and negatively affects sperm activity.
Start and complete the course.
Get a full medical examination.
Treat bad teeth if you have such problems.
Follow a daily routine - alternate rest with work.

If a man decides to become a father, then baths, saunas and hot baths are contraindicated for him, since all this negatively affects the quality of sperm.
If a man is fond of cycling or riding a horse, then these activities should be abandoned while planning pregnancy, since the friction of the scrotum, which occurs as a result of horse riding, increases its temperature, and this has a very bad effect on sperm.
Six months before trying to conceive a child, it is necessary to stop taking steroids or any other pharmacological drugs, if the man has taken them.

Avoid all types of vaginal lubricants and douching. All this kills the natural environment in the vagina, changes its acid-base balance and destroys sperm. It’s better to take advantage of products that can stimulate conception.
During sexual intercourse on the day when the conception of a child may occur, you need to apply the necessary for this purpose. It is best if ejaculation into the vagina occurs when the man is on top. After ejaculation, a woman should not move, but should lie quietly for half an hour, placing a pillow under her buttocks.
If a woman has been taking birth control pills for a long time, the likelihood of pregnancy may increase only a year and a half after stopping taking them.

Conclusions

Once you decide to get pregnant, don’t get hung up on it, even if your desire to become parents is very strong. You must understand that pregnancy may not occur immediately, even if you correctly calculate the conception calendar. And waiting every month for the first signs of pregnancy, which never make themselves known, you will be upset, and this is extra stress for the body, which can only harm the process of conceiving a child. Let go of the situation and enjoy your loved one. Let everything take its course, just do everything that depends on you on your part.

Video “Favorable days for conceiving a child”

In this video, obstetrician-gynecologist at the CIR clinic, Elena Valerievna Govorkova, talks about all sorts of ways to determine favorable days for conceiving a child.

From time immemorial in Rus', children were conceived in the fall and born in late spring and summer. The time for weddings was in October. This was due to religious traditions and the season of field work.

Just in September, the time for harvesting ended, and the peasant could rest. And as you know, everyone worked in the fields - both men and women. It is not difficult to understand how this affected the health of children, who were hardened and accustomed to work from an early age.

But if we consider the time of conception and birth from a scientific point of view, then each season can find its pros and cons. Choose what is more important to you and decide for yourself.

Conception in summer - birth of a child in spring

Pros

Lots of vitamins (fresh fruits and vegetables), good health.
Minimal risk of contracting acute respiratory infections and flu.
An opportunity to relax at sea and gain strength.
A lot of positive emotions in connection with the holidays in the summer.

Cons

The last months of pregnancy take place during the flu season and an increased likelihood of injury (ice, slush). Hardening up on the eve of pregnancy, a sports lifestyle and vitamins, as well as accompanying your husband during walks will help you.
Childbirth takes place during a seasonal weakening of the body and a deficiency of natural vitamins - load up on vitamins in the fall and winter, and take tablets in the spring.

Conception in autumn - birth of a child in summer

Pros

Lots of vitamins during conception (fruits, vegetables).
You can relax during the velvet season in the south and get positive emotions.
Lactation also falls during a period rich in vitamins.
Less chance of seasonal injuries.

Cons

The first months of pregnancy occur during the cold season, which poses a danger to the fetus. Prepare well for conception: harden yourself and take vitamins.
The last months of pregnancy are summer. If the weather is hot and stuffy, it is difficult to bear, especially with late toxicosis - buy a fan and do not go outside during the day, but walk in the evening or early in the morning, when the air is fresh and there is no stuffiness.
Long daylight hours are not conducive to the production of the pregnancy hormone melatonin, which is very important in the last months. The pineal gland produces the hormone mainly at night, so it is most abundant in late autumn and winter. If you're healthy and happy, you'll get through pregnancy with the amount of melatonin you have.

Conception in winter - birth of a child in autumn

Pros

In the last months of pregnancy there are many natural vitamins (fruits and vegetables). They are especially necessary for the fetus for birth and the adaptation period.
Lactation also takes place under conditions of vitaminization of the body.

Cons

The first months of pregnancy are at the peak of influenza and acute respiratory infections epidemics. This is very dangerous, since in the first two months the formation of the main organs of the child occurs. Protect yourself from infections with vitamins and a healthy lifestyle.
Towards the end of pregnancy, the production of the pregnancy hormone melatonin decreases. This is not scary for a healthy and seasoned body.
The first months of a baby's life fall during the cold season - this is not very good for walking. If the child is healthy, they begin to harden him from the first days (air baths, etc.), and walk with him in any weather (a stroller and a hood will protect him from wind and rain).

Conception in spring - birth of a child in winter

Pros

Conception occurs during the most joyful period of nature's rebirth - the season of love. It brings a lot of positive emotions.
The last months of pregnancy occur in favorable conditions, when the vitamin reserve has not yet been depleted.
In the last months of pregnancy, the production of melatonin, the pregnancy hormone, is highest.
Good weather conditions to make it easier to tolerate late toxicosis (it’s not hot outside).

Cons

During the period of conception, parents may experience vitamin depletion, which is observed in most people in the spring. Take vitamins.
In the last months of pregnancy, there is a high probability of injury (ice, slush).
The first months of a baby’s life fall during an epidemic of influenza and acute respiratory infections - harden and take care of the child, use oxolinic ointment.
Not very good conditions for walking in cold and windy weather - dress your child according to the weather, buy a reliable stroller with a hood.

As you can see, any disadvantages can be overcome and even turned into advantages, for example, bad weather is good for hardening a child. In addition, in the first months the baby is reliably protected by maternal immunity, which he received at birth and continues to receive from breast milk; he is not so afraid of viruses. The main thing is that the child is dressed appropriately for the weather, and not sweating in several layers of clothing. But more on that in another section.

Elena endured pregnancy easily, despite the fact that she was worried a lot. Although she was a suspicious woman, she did not have toxicosis. The baby was due in the spring. According to her calculations, just on her husband’s birthday.

It was late spring outside. The snow had melted long ago, but the weather was terrible - rain, wind, then sleet again, cloudy. This did not put the already worried woman in a good mood. Therefore, a week before the expected birth, Lena decided to go to the prenatal department, fortunately the doctor was a good friend and provided her with all kinds of care and concern.

My son was just a day shy of my husband’s name day; he was born on April 20th. On this significant day, even the sun came out to greet the baby. It flooded the mother's room and smiled at the baby. Day by day the baby became healthier, and the weather softened. Contrary to all forecasts, on the day of discharge the sun was shining brightly and the kidneys were already about to swell.

It will be good to walk with Ilyusha,” the young mother rejoiced. As the doctors advised, the very next day mom and dad decided to take the little one for their first walk. It got a little colder outside and the sun treacherously disappeared, but they dressed the baby warmly and went to the park. It was about a kilometer to walk to get there, but it was a walk. On the way back, a surprise awaited them - wet snow began to fall. The strong wind knocked the parents off their feet, but the baby dozed peacefully in his stroller. Its walls reliably absorbed the attacks of the wind, and the hood protected from snow.

The parents were wet and cold, but the baby didn’t care, although Lena was very worried about the baby. This snowy, cold weather continued for another month, but the parents walked with the child every day. As a result, Ilyusha became stronger and did not get sick at all for the first year.

Favorable days for conception

When the necessary tests have been passed, vaccinations have been made, a healthy lifestyle has been established, and even the desired time of birth has been chosen, there is little left to do - just get pregnant. To do this, you need to know the most favorable days for conception. They are quite easy to calculate if you have an average menstrual cycle. Otherwise, your gynecologist will help you.

The average woman's menstrual cycle is 28-30 days. It begins with the first day of menstruation and ends with the first day of the next menstruation. If the cycle is stable and repeats every month with exactly the same break, you can safely begin calculations. During the first half, a follicle matures in one of the ovaries, from which a mature egg is released, and on the 14-15th day after this, that is, its maturation occurs.

A mature egg is capable of fertilization within two days after ovulation, and sperm have fertilizing activity within 4 days after ejaculation. Therefore, the total period of the most probable possibility of conception is about 6 days.

So, we count 14-15 days from the start of menstruation - this will be the first day of possible conception. We add 6 days to it, during which conception is also possible. During this period, intensify your sexual relationships, and pregnancy will be most likely.

Discussion

I wanted to comment, but changed my mind...
The article may still be useful for those who do not have any problems with conception and everything turns out right away as they wanted. And thank God!

From time immemorial in Rus' only one child was born, which was conceived exclusively on the wedding night.... Funny.
I tried to plan my children, especially the second one, so that the pregnancy would not fall in August-September, when my seasonal allergies reach their peak and sometimes it seems that I’m just about to suffocate. Failed. But waiting for a favorable period for the next year (and then the next, then another..) was somehow out of the question, in case the childbearing age passed altogether.

With the help of a conception calendar, a woman can control her menstrual cycle, calculate ovulation and days when the probability of becoming pregnant is higher.

Conception calendar- this is a form in which you just need to enter the number of the first day of your last menstruation, and a special program will automatically calculate the possible days of conception, highlighting them in different colors. Using this calendar is very simple and effective.

To understand the effectiveness and main provisions of this program, consider the following factors that were taken as the basis for its construction:

Women have one day of ovulation, when the egg is mature and ready for fertilization. This day is in the middle of the menstrual cycle. In the conception calendar, this day and a couple of days before and after it are highlighted in red and orange.
days on which it is almost impossible to get pregnant (if you have a regular menstrual cycle) are highlighted in white on the calendar. These days occur during menstruation and at the end of the cycle.

To check the effectiveness of this program, monitor the state of your body during ovulation:

1. there is an increase in the amount of vaginal discharge;
2. sexual desire increases;
3. the temperature in the rectum increases;
4. the ovulation test shows a positive result;
5. the appearance of short-term aching pain in the area of the ovaries and uterus;
6. Ultrasound shows signs of the release of an egg from the ovary.

To calculate the days of possible conception and the date of ovulation right now, you need to enter the specific date of the start of menstruation, and within a few seconds you will receive the necessary information.
But please note that you cannot rely entirely on these calculations. This happens because the processes in our body can be affected by a change of place of residence, stress and much more.
In addition, ovulation does not occur in every cycle. With this in mind, every woman has cycles that are “infertile.”

Color meaning

The most likely day of ovulation, the best day to conceive.
The probability of conception is 90%.
The probability of conception is 80%.
Your first day of your period.

For a representative of the fair sex, on the one hand, it is easy to get pregnant, but on the other, it is difficult. Why is there such duality? Let's turn to physiology. In a woman of reproductive age, it happens every month around the middle of the cycle. This term refers to the release of a mature egg from the ovary. This process takes only 1-2 days.

Many people, having read the text written above, will probably think that getting pregnant is very simple - you just need to calculate the day of ovulation, and have sex with your partner before and after it. However, everything is not as simple as it seems. If it were possible to get pregnant strictly in the middle of the cycle, then there would be no unwanted pregnancies and women who dream of a child, but cannot get pregnant for some reason.

On what days is it impossible to conceive a baby?

We will disappoint women who have chosen the calendar method of contraception and refused other means of protection (condoms, various drugs), because there are no absolutely safe days. You can get pregnant at any time. You only need to take into account that on some days the chances of conceiving a baby are great, while on other days they are significantly reduced. There are no periods with zero probability.

A relatively “safe” time can be considered a couple of days before menstruation and a couple of days after it. To calculate “dangerous” days, you need to know the duration of the menstrual cycle. It must be stable - this is the main condition.

With a 28-30 day menstrual cycle, the highest chances of conception occur on days 14-15, since ovulation occurs around this time. Deviations are also possible for a number of reasons: due to nervous breakdowns, stress, the presence of diseases, and the use of medications.

How to calculate without errors what days you can get pregnant?

Calculating the days on which you can conceive a child is not so easy. To do this, you need to analyze the entire menstrual cycle, taking data for the last 6-12 months. If hormonal contraceptives were used at this time, the calculation results may be incorrect.

In order not to forget what days your period occurs, you should create a special calendar. If the menstrual cycle is not regular, then it will not be possible to determine on which days you can get pregnant. It is best in such cases to use other methods of calculating favorable periods for conception.

If minor deviations are observed during the time period under study, then the following step-by-step calculation can be made:

Identify the longest and shortest menstrual cycles for 6-12 months;
Subtract the number 18 from the number of days of the short cycle. The result obtained is the day from which the period with a high probability of getting pregnant begins. For example, the shortest cycle is 25 days. Subtracting 18, we end up with the number 7. This means that the favorable period for conception begins on the 7th day of the menstrual cycle;
Subtract the number 11 from the number of days of the longest period. The result obtained is the day that ends the period with a high probability of getting pregnant. For example, the longest cycle is 29 days. Subtracting 11, we get the number 18. Thus, on the 18th day of the menstrual cycle, the favorable period for conception ends;

From this example it is clear that the highest probability of becoming pregnant remains from the 7th to the 18th day.

Is it possible to conceive before menstruation?

A definite answer to this question cannot be given. Conception may or may not happen. First, let's figure out why the above question can be answered in the negative.

As you know, ovulation occurs in the middle of the cycle. Before the start of menstruation, the egg dies. If ovulation occurs much later or repeatedly, then an interesting situation may not occur, since the woman’s hormonal background will be adjusted to a new cycle.

Now we will explain why conception can occur before menstruation. Healthy women who have irregular sex life have a fairly high chance of becoming pregnant. Conception can occur after any sexual intercourse.

The body can react to such a rare event with unscheduled ovulation. It can also be triggered by substances contained in semen. Women who regularly have sex with a regular partner may not encounter this.

Is it possible to conceive during menstruation?

Pregnancy during the first days of menstruation is unlikely. This is explained by an unfavorable environment for sperm and for embryo implantation (excessive bleeding). However, “surprises” from nature should not be excluded.

Conception during an unfavorable period can occur in the following cases:

with prolonged menstruation (for example, there may be less than a week left before ovulation, and then the sperm will wait for the release of a mature egg);
due to menstrual irregularities caused by diseases, infections, physical activity, stress;
if the period of safe sex is incorrectly calculated (due to the irregularity of the menstrual cycle).

Is it possible to conceive immediately after menstruation?

Many representatives of the fair sex claim that it is impossible to get pregnant within a few days after the end of menstruation. Doctors do not adhere to this point of view. They warn that you can get pregnant at any time.

Sperm entering the female genital tract can remain viable and active for several days. If the menstrual cycle is short and the periods are long, then the probability of becoming pregnant will be high. Sexual intercourse can take place during the most favorable days for conception.

Pregnancy immediately after menstruation can occur for the following reasons:

due to the ability of sperm to maintain their activity for several days;
due to the maturation of several eggs in one menstrual cycle;
due to a shift in the time of ovulation. It may not occur in the middle of the menstrual cycle, but much earlier or later. The “culprit” of such disorders in young girls is the irregularity of the menstrual cycle, and in adult women – hormonal abnormalities.

Based on this, we can say that the calendar method is not a reliable means of contraception. For some women it is not suitable at all.

During what period you are most likely to get pregnant: ways to determine

You can calculate the most favorable days for conception not only using the calendar method. There are several other more effective ways:

Determination of basal temperature;
Carrying out ovulation tests;
Folliculometry;
Subjective feelings.

1. Determination of basal temperature

To calculate the period when the probability of conceiving a child is high, it is necessary to measure the basal temperature in the anus every morning after waking up from the beginning of the menstrual cycle (from the 1st day of menstruation).

Errors can occur for several reasons:

due to overwork or illness (during such periods the temperature is always elevated);
if you drank a lot of alcohol before the measurement;
due to taking certain medications;
if sexual intercourse occurred 6 hours (or less) before measurement;
due to lack of sleep.

Based on the measurement data, a graph should be drawn up that can be updated daily with new results. In the first half of the menstrual cycle, the temperature ranges from 36.6 to 36.9 degrees. It rises above 37 degrees after the release of a mature egg.

You can find out when ovulation occurs by carefully studying the chart. On days 12-16, basal temperature may decrease slightly. This will herald the onset of ovulation in the coming hours. This is the period during which you can get pregnant. At this time, women dreaming of a baby should have sex.

2. Carrying out ovulation tests

Modern and more accurate means of determining the release of an egg are ovulation tests. They are even similar to tests that can be used to find out if you are pregnant. The result is shown as 2 bars. The only difference between the tests is the reagents. For example, ovulation detectors contain a substance that responds to the presence of luteinizing hormone (LH), the level of which increases in the body 23-36 hours before ovulation.

In order not to miss the long-awaited event, you need to take tests every day and at the same time. After ovulation, LH levels drop significantly, and then the strips begin to show a negative result. Manufacturers producing ovulation tests include several strips in the package. Thanks to this, this method of determining favorable days for conception is as justified and convenient as possible.

3. Folliculometry

Diagnosing the period during which you can get pregnant is very simple using ultrasound(ultrasound). This method cannot be called economical. It is suitable for those representatives of the fair sex who want to conceive a child, but they just can’t do it.

It is recommended to visit the ultrasound room from the 10th day after the start of the last menstruation. Over the course of several days, your doctor will evaluate the growth of the dominant follicle in the ovary. When it reaches a size of 18-24 mm in diameter, an egg ready for fertilization will be released. Follicle formation may not lead to ovulation. It may not rupture, but regress. Such cases are rare, but they do occur in real life.

The main signs of the onset of a favorable period for conception, which a medical professional sees on the monitor during an ultrasound, are the corpus luteum located in the ovary without a dominant follicle, as well as some fluid behind the uterus.

The quality of the endometrium influences the onset of pregnancy. It is known that an egg fertilized by a sperm must be implanted into the uterine wall for subsequent development. If by the time of ovulation the endometrium does not reach a certain thickness, then pregnancy will not occur, since the fertilized egg will not be able to attach to the uterus and will die.

4. Subjective sensations

This method is not 100% reliable, but many women who are sensitive and attentive manage to determine the days on which the probability of becoming pregnant is high. Every month the sensations are repeated. If you listen to your body, you can draw some conclusions.

The most common signs of a favorable period for conception are:

the occurrence of pain in the lower abdomen or the location of one of the ovaries;
sudden increase in sexual appetite;
copious vaginal discharge. They can be easily noticed by any experienced gynecologist. Discharges are different from symptoms of infectious diseases. They are colorless and odorless. After 2-3 days, the discharge disappears without a trace until the next cycle.

Representatives of the fair sex undergo 1-2 times a year cycles called anovulatory. They represent a kind of “reboot” of the female body. It is impossible to get pregnant at this time. These days can be determined very easily. Here are their main features:

when measuring basal temperature, no jumps are observed;

The achievements of modern medicine allow a woman not only to live a full sexual life without fear of unwanted pregnancy, but also to calculate the time most favorable for conceiving a child.

How to make a conception calendar

Conception is the process of fusion of an egg and a sperm; it is from this moment that a new life appears and begins to develop. It is impossible to accurately calculate when this great sacrament takes place, but it is possible to determine from a woman’s menstrual cycle the time when this is most likely to happen.

The egg in the female body matures towards the middle of the menstrual cycle. When the egg is mature and ready for fertilization, it is carried into the fallopian tube. This moment is called ovulation.

In order for a person to conceive, sexual intercourse must take place at the earliest - 4 days before ovulation, and at the latest - a day after it. This condition is due to the fact that after sexual intercourse, those sperm that managed to reach the fallopian tube can wait no more than 4 days for the egg to appear there, and then they die. An unfertilized egg can live for 24-72 hours. Therefore, for a planned conception, it is important for a woman to draw up a special calendar and know the most favorable days for sexual intercourse.

To compile such a calendar, a woman must calculate the duration of her menstrual cycle, since the day of ovulation falls approximately in its middle, and best days to conceive are five days: 3 days before ovulation and 2 days immediately after it. Many calendars calculate 4 days before ovulation and 4 after, since the process of releasing the egg can vary in the time interval between three days. Thus it is possible.

You need to count from the first day of your period (that is, inclusive, the days of menstruation). The length of the cycle may vary, so you will have to monitor it for several months, but even in this case, it is quite difficult to calculate the exact period of ovulation.

Therefore, when calculating the time of ovulation, additional methods are used. The most accurate of them is an ultrasound scan during expected ovulation, but this method is not very convenient, since several procedures may be required during each intermenstrual period.

A slightly less accurate, but much more convenient method is an ovulation test, which is sold at the pharmacy.
And the third way is to measure basal temperature (rectal). In order for this method to work, the temperature must be measured in the morning, without getting out of bed, and recorded over several cycles. This method requires patience and discipline, but the accuracy of the results will still be relative.

Thus, the most optimal method for drawing up a conception calendar is the following: calculate your cycle, and then, within 1-2 periods, use an ovulation test to determine the day on which it occurs. If your cycle is stable enough, then after 3-4 periods you will receive an individual and fairly accurate conception calendar.

Calculate favorable days for conception

If you have already compiled a calendar for your menstrual cycle, then you can begin to calculate days favorable for conception. For the most accurate calculation, you will need to have a calendar for at least 3-4 months.

Now calculate the day on which you ovulate. As a rule, with a twenty-eight-day cycle, the release of the egg occurs approximately on the 14th day. In a short cycle of 26 days, ovulation occurs on the 12th day, and in a long cycle (30 days) - on the 16th day. Possible deviation is 3 days. Therefore, to accurately determine the day of egg release, you need to start doing tests approximately 4 days before the expected date.

If the result is negative, continue testing daily until the result is positive. Once it is received, mark the day of ovulation on your calendar. During the next month, begin intimate relationships with your partner with the goal of conceiving approximately 4 days before the calculated date of ovulation, sexual intercourse is also desirable on the day the egg is released and within 2 days after it. This recommendation is based on the lifespan of the sperm and egg.

Keep in mind that pregnancy may not occur even with careful calculation of days favorable for conception, since a healthy woman of reproductive age has cycles when the egg does not release from the ovary. In this case, the attempt should be repeated on favorable days of the next period and during sexual intercourse, positions most suitable for fertilization should be used.

Calculate the day when conception occurred if pregnancy has already occurred

Is it possible to calculate the exact day of conception of a child in the case when pregnancy has already occurred? If you are in the habit of keeping a menstrual calendar, then this will not be difficult to do. You just need to find out the date of the first day of the last menstrual cycle.

About halfway through your cycle, you ovulated. Now all you have to do is remember whether you had intimacy with your partner 4 days before ovulation on the day of ovulation or 2 days after it - and you will know the day your child was conceived.

It will be more difficult to determine the day of conception if you do not keep a calendar and cannot remember the start date of the last menstrual cycle before pregnancy. In this case, we can advise you to buy a pregnancy test, which shows not only the presence of pregnancy, but also its duration. To be more confident, also undergo an ultrasound scan, compare the test results with the ultrasound results, and calculate the date of conception.

There is an obstetric pregnancy period and an embryonic period. Obstetricians calculate the date from the last menstrual period. Embryonic, that is, the actual period of pregnancy, from the day of conception. Therefore, the difference may be about 2 weeks. The obstetric period is longer than the actual one - embryonic, because during the first day of menstruation, the birth of a new life is unlikely to occur.
