The best time to conceive a child is before your period. What are the best days to conceive a child

To conceive a baby, you need to choose a good time so that everything goes well. It can be selected with the help of a consultation with a gynecologist, or information provided by various Internet sites, or you can use literature suitable for this topic. There is another option that you should pay attention to - creating your own conception calendar.

When compiling such a calendar, you need to know when ovulation occurs. And so you need to have an idea of how long the cycle of menstruation is, for example 28-30 days. It is important to calculate ovulation days when planning a pregnancy before it occurs 2-3 months in advance. This will make it easier to determine the accuracy of the cycle.

The process of ovulation lasts 4 days and usually happens in the middle of the menstrual cycle. These days are the most favorable for those who are preparing for pregnancy. The female cervix has the most sensitive mucous membrane during this period, so the moment of penetration of the sperm into the egg is most likely to take place here.

To more accurately establish the ovulation day, you can resort to ultrasound. This procedure allows you to monitor the growth of the follicle and identify the exact time of its rupture.

To prepare for the onset of pregnancy, you can also use the morning measurements of basal temperature. Usually the procedure is done at the same time using an ordinary thermometer. The obtained data is displayed on a graph, the horizontal axis of which is the day of menstruation, and the vertical axis is temperature. Before the temperature should rise by 0.2 - 0.4 degrees, there is a slight decrease in it. Just the gap between these two phenomena can be ovulation. To accurately determine the process of ovulation, it is important to draw such a graph regularly. The data displayed on the graph may also be useful to the gynecologist during consultations with him.

The onset of the ovulation process can also be calculated while at home, thanks to tests that are carried out on the 9-15th day of the monthly cycle a couple of times a day. They show the presence or absence of a peptide hormone. In the event that it is detected, ovulation should occur in 16-28 hours.

For the onset of conception, you can use the above, however, if you want to get pregnant at a certain time of the year, you need to make a pregnancy calendar.

Conceiving in winter will benefit the newborn baby in the form of warm weather, he will have the opportunity to adapt before the onset of colder weather conditions.
The onset of pregnancy in the spring promises the birth of a dear person during the New Year holidays and Christmas. However, during the waiting period for the birth of the baby, the expectant mother will need to endure the hot summer and the ice season as winter approaches.
When conception occurs in the summer, the expectant mother can consume as many berries and fruits as she wants. But intense heat will cause edema in a pregnant woman, so you need to be extremely careful. In this case, you will have to take into account that the time for childbirth will be cold, and the baby will need to be given maximum attention in order to prevent colds and chills.
Conceiving a child in the fall, you can not limit yourself to the number of walks in the fresh air that are useful for the expectant mother and baby. Autumn is the time to consume vitamins, but you should also be wary of various infections.

Summing up, we can say that it is really possible to choose the time of year for the birth of a crumb and plan its conception correctly. But do not forget that in pursuit of the desired period of childbirth, you can digress from the most important thing - the health of the child, you just do not need to forget about it.

Each woman with sufficient accuracy can determine the time of ovulation that occurs in her body. By measuring her body temperature daily and noting the results, she will notice that about 14-15 days from the first day of the cycle, the woman’s body temperature will rise slightly and will remain at this level until the end of the cycle.

FAVORABLE DAYS FOR CONCEPTION.WHEN IS THE BEST TO GET PREGNANT?

With a menstrual cycle of 28 days, the most favorable time for conceiving a child is the 14th and 15th days from the first day of the onset of menstruation. The beginning of the next cycle is the end of menstruation (menstruation), when, under the influence of the follicle-stimulating hormone of the pituitary gland, a new follicle begins to grow and develop. It is on these days that the mature follicle ruptures and the egg is released from it, ready for fertilization. And if seminal fluid enters the vagina, and there is a sufficient amount of good quality spermatozoa in it, and besides, they successfully go all the way to the egg (cervix - uterine cavity - fallopian tube), and at least one spermatozoon will come "to meet" with an egg without delay, then there is a high probability that fertilization will take place.

IT IS IMPORTANT! If sexual intimacy takes place on the indicated days, this is not a guarantee that pregnancy will definitely occur. Often, in young and healthy couples, the desired conception occurs only after many months of marriage, and even more time may be required. In this regard, one should not be especially worried and assume an inability to ovulate, obstruction of the fallopian tubes, or infertility of a partner.

Statistical studies say that in about 90% of healthy couples, attempts to conceive a child are crowned with success within a year from their start, and the fact that success does not come immediately is not a reason for concern, joint visits to the doctor and examination for infertility. The most likely cause of "failure" is fatigue and excessive anxiety.

MEN:

2. It is not advisable to ride a bike or ride a lot. Constant friction of the scrotum leads to an increase in temperature and greatly reduces the quality of sperm.

3. Steroids and muscle growth stimulants are not desirable for future fathers. Refusal to take them must be done no later than six months before trying to conceive a baby.

WOMEN:

1. During conception, it is recommended to abandon vaginal lubricants. Vaseline-based creams may contain substances that change the acid-base balance of the vagina and destroy sperm. Douching has the same effect, which should also be abandoned during this period. In addition, often used, it reduces the natural protective function of the vaginal flora. As a result, the risk of infection increases.

2. When having sex, the position of partners is of great importance. In the “man on top” position, the loss of sperm will be minimal, and its penetration will be maximum. After ejaculation (ejaculation) of a man, a woman needs to lie on her back for 30 minutes, lifting her pelvic region or placing a pillow under her pelvis. This will increase the chances of conception. If a woman at the time of conception for some reason has only one ovary, then after ejaculation, the woman needs to raise the pelvic region and turn on the side where the ovary is.

3. When conceiving, it is important to choose the right day. The egg is ready for fertilization within 2-3 days. Sexual intercourse does not necessarily have to coincide with the moment of its maturation, but it is better if it is closely tied to this moment. It's easy enough to predict. Usually, the egg is ready for fertilization 14 days before the end of the cycle. If it lasts 28 days, then it will be the 14th day from the beginning. With a cycle of 32 days - the 18th.

4. When a man "works hard", sperm production drops sharply. If ejaculation occurs at long intervals, this is also bad: not so much the number of spermatozoa decreases, but their mobility - they are no longer so actively rushing towards the goal. During the maturation of the egg, it is best to have sex once every 2 days. For a woman with a 28-day cycle, these are the 12th, 14th and 16th days of it. And during the 4 days preceding the possible period of conception, it is better for a couple to abstain from sex. But after the 16th day, you can relax and have fun.

5. If before the decision to become pregnant a woman took contraceptives, then it is reasonable to wait 15 months: after many years of taking birth control pills, it takes time to normalize the menstrual cycle. If a woman is over 30 and she has not used birth control pills, it is enough to wait about six months. There is no reason to delay with this longer: the longer it is not possible to get pregnant, the more difficult it is for a specialist to provide effective assistance. And after 35, modern methods of infertility treatment do not work at all. If the woman is not yet 30, it is reasonable to wait 1 year. In the event that pregnancy does not occur during this period, you need to seek help from medicine. The better at the time of conception the physical and mental state of the future father and mother, the healthier the child will be.

IT IS IMPORTANT! Before getting pregnant, it is advisable to do the following:

– undergo an examination – if you need to be treated;

- heal unhealthy teeth;

- have a good rest (on vacation);

– reduce contact with household chemicals;

- reduce the consumption of pharmacological agents;

- reduce sexual activity.

Most women who decide to prepare for conception in advance stop using protection and begin to carefully monitor their body, keep a calendar so as not to miss the so-called “favorable days” necessary to conceive a healthy baby.

After it happens, the egg becomes capable of fertilization. There is plenty of time for a man and a woman to conceive a child.

Sperm, getting into the female body, as a rule, live up to five days. The female body allocates five favorable days before ovulation and 15 hours after it. Therefore, it is on these days that the probability of pregnancy is maximum.

The most successful day for conception, one can say peak, win-win, is the day of ovulation itself.

To accurately determine the right day, a woman can make an individual conception schedule herself.

Individual schedule for conceiving a child

What is required for this?

Grab a handy calendar where you can make graphic and color changes.

Now it is time to apply the knowledge and all the information about the menstrual cycle. Such data is necessary for accurate calculation of favorable days.

To start calculation:

write the date of the first day of the last menstruation;
indicate the length of your menstrual cycle;
indicate how many days the period lasts.

For example, the menstrual cycle is 28 days. The duration of menstruation is 6 days. The first day of menstruation is November 24th. It is believed that with a 28-day cycle, ovulation occurs on days 14-16. Count from the first day of the month 14 and 16 and mark these dates on the calendar (in our example, they fall on December 7 and 9). You add 5 more days to these days, and it turns out that the days from December 7 to December 14 will be the most favorable for conception. The error in the calculations can be plus or minus 2-3 days.

Measurement of basal temperature

The most famous way to determine favorable days for conception is measurement. And the most amazing thing is that with the help of this method you can generally learn a lot about the state of your body - in fact, you can independently undergo an examination. However, we advise you to refrain from the temptation to unprofessionally diagnose yourself and even more so prescribe treatment.

Basal temperature is the body temperature at rest, during the monthly cycle it changes under the influence of various hormones in the female body.

The data of the basal temperature chart will allow you to find out:

the moment of maturation of the egg;
expected time of ovulation;
How does the endocrine system work?
whether there are gynecological problems;
the exact schedule of the menstrual cycle, the beginning of menstruation;
confirm the fact of pregnancy.

What is necessary? Medical thermometer. The ideal option is an electronic thermometer. In a few seconds, he will measure the temperature and himself will let you know about this with a characteristic signal.

Exists: in the mouth, in the rectum, in the vagina. The most reliable result is obtained by measuring the temperature in the rectum.

In order for the process of measuring basal temperature to be successful, it is better to prepare everything in the evening. Find a place for the thermometer next to your bed. If you decide to use a mercury thermometer, be sure to follow the safety rules. Do not put it without a case, especially under the pillow, so that in the morning, waking up, you do not accidentally break it.

Waking up, you can not get up - you should immediately, in the supine position, measure the temperature. In order not to forget the result, try to immediately write down the readings in a notebook, which, like a thermometer, should be kept in a convenient, easily accessible place.

It is best to measure the temperature at the same time. Of course, there may be exceptions, for example, Sunday sleep often lasts longer, but in this case, be sure to make a note on the schedule. Why is such precision needed? It's all about the state of the body. Every hour of sleep raises your basal body temperature by 0.1 degrees.

The accuracy of temperature determination also depends on the “quality” of sleep. It must be continuous for three hours.

To build a graph, you need to remember how the abscissa and ordinate axes look like. After drawing the y-axis, mark the degrees (each cell means 0.1 degrees). The days of the menstrual cycle are placed on the abscissa. Notes can be given a separate place. These can be records of the state of cervical mucus, various causes that affect the temperature: illness, stress, poor sleep, alcohol intake, and others.

At each temperature level in the morning, put a point, and so on throughout the cycle. Then connect all the dots with one line. To get an accurate schedule for measuring basal temperature, try to bypass when connecting the points of the place "very high" or, conversely, "low" temperature, associated, according to your notes, with some kind of negative events or influences.

The graph of temperatures of the last cycle is built. It is of direct importance in determining ovulation. If you look closely at it, you can accurately note the decrease in the temperature curve during menstruation (first phase). The day when it begins to decrease, as well as the total duration of the decrease process, is individual for each woman. At the onset of the last days of menstruation, the temperature is equal to the level of the follicular phase of the cycle. This is a period of low temperatures. The temperature mark at such moments corresponds to 36.2-36.5 degrees. These temperature indicators are influenced by estrogens, which are released in large quantities.

The second phase - luteal - comes into its own approximately 14 days before menstruation and is a phase of higher temperatures. It is on the border between low and high temperatures that ovulation occurs. Ovulation is marked by a decrease in temperature by 0.1 degrees, and then a sharp rise. Usually, during ovulation, the temperature in the vagina and rectum drops, sometimes even to 36.2-35.9 C. It often happens that there is no decrease. This means that the day of ovulation is considered to be the one that precedes the day when the temperature rose. To be more accurate in determining ovulation, compare all the signs, namely: the marked basal temperature and the state of the cervical mucus.

When pregnancy occurs, the temperature will stay at 37.1-37.3 degrees. If menstruation is due, the temperature will drop the day before.

Let's generalize. The normal basal temperature chart is biphasic. The temperature in the 1st phase of the menstrual cycle is kept at the level of 36.4-36.7 C, however, individual fluctuations are possible.

On the day corresponding to ovulation, the temperature decreases by 0.3 C, and then within 1-2 days it rises by 0.6 C, compared with the 1st phase. Elevated temperature should be maintained for 11-14 days. In the absence of ovulation, the formation of the corpus luteum does not occur, respectively, progesterone is not produced and there is no increase in temperature.

Especially for- Olga Pavlova

The fair sex, on the one hand, is easy to get pregnant, but on the other, it is difficult. Why is there such a 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, after reading the text written above, will probably think that getting pregnant is very simple - you just need to calculate the day of ovulation, and before and after it, have sex with your partner. However, everything is not as simple as it seems. If it was 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 are sorry for 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. It is only necessary 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 them. 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 the 14-15th day, since ovulation occurs around this time. Deviations are also possible for a number of reasons: due to nervous breakdowns, stress, the presence of diseases, the use of drugs.

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

Calculating the days on which you can conceive a child is not so simple. 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 that time, the calculation results may be incorrect.

In order not to forget what days menstruation occurs, you should create a special calendar. If the menstrual cycle is not regular, then it will not work to determine 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 studied time period, then the following step-by-step calculation can be made:

Select the longest and shortest menstrual cycles for 6-12 months;
Subtract the number 18 from the number of days of a short cycle. The result obtained is the day from which the period with a high probability of becoming 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 from 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 on which the period with a high probability of becoming pregnant ends. 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 can be seen that the highest probability of becoming pregnant remains in the period from the 7th to the 18th day.

Is it possible to conceive before menstruation?

An unequivocal answer to this question cannot be given. Conception may or may not occur. First, let's see why the above question can be answered in the negative.

As you know, ovulation occurs in the middle of the cycle. Before the onset 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 set to a new cycle.

Now we will explain why conception can occur before menstruation. In healthy women who have an irregular sex life, the chance of getting pregnant is quite high. Conception can occur after any sexual intercourse.

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

Is it possible to conceive during menstruation?

Pregnancy during the first days of menstruation is unlikely. This is due to the unfavorable environment for spermatozoa and for implantation of the embryo (abundant bleeding). However, "surprises" from nature should not be ruled out.

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

with prolonged menstruation (for example, less than a week may remain 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;
with an incorrect calculation of the period of safe sex (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 at any time you can get pregnant.

Spermatozoa 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 chances of getting pregnant will be high. Sexual intercourse can just take place during the most favorable days for conception.

Pregnancy immediately after menstruation can occur for the following reasons:

due to the ability of spermatozoa to maintain their activity for several days;
due to the maturation of several eggs in one menstrual cycle;
due to the timing of ovulation. It can happen not 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.

What period is most likely to become pregnant: ways to determine

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

Determination of basal temperature;
Conducting 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 a lot of alcohol was drunk before the measurement;
due to taking certain medications;
if sexual intercourse occurred 6 hours (or less) before the measurement;
due to lack of sleep.

Based on the measured data, a graph should be drawn up, which can be supplemented 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 if you carefully study the schedule. On days 12-16, the basal temperature may slightly decrease. This will herald the onset of ovulation in the coming hours. That's when you can get pregnant. At this time, women who dream of a baby should have sex.

2. Conducting ovulation tests

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

In order not to miss the long-awaited event, you need to do tests every day and at the same time. After ovulation, the LH level drops significantly, and then the strips begin to show a negative result. Manufacturers that produce ovulation tests put several strips in the package. Due to this, this method of determining favorable days for conception is the most justified and convenient.

3. Folliculometry

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

It is recommended to visit the ultrasound room from the 10th day after the start of the last menstruation. Within a few days, the 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 come out of it. The formation of the follicle may not lead to ovulation. It may not break, 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 worker sees on a monitor during an ultrasound scan, are a corpus luteum located in the ovary without a dominant follicle, as well as a little fluid behind the uterus.

The quality of the endometrium affects the onset of pregnancy. It is known that an egg fertilized by a sperm must be implanted in 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 feelings

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 the onset 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. Any experienced gynecologist can easily notice them. The discharge is different from the symptoms of infectious diseases. They are colorless and odorless. After 2-3 days, the discharge disappears without a trace until the next cycle.

The representatives of the fair sex have 1-2 times a year cycles called anovulatory. They represent a kind of "reboot" of the female body. At this time, it is impossible to get pregnant. It is very easy to determine these days. Here are their main features:

when measuring basal temperature, jumps are not observed;

Every woman sooner or later decides to become a mother. But not everyone succeeds the first time - sometimes pregnancy has to wait quite a long time. And in such cases, the question arises of what time is optimal for its onset, in particular, whether conception can take place after menstruation. To answer this question, it is necessary to consider the principles of the functioning of the female reproductive system and the main points regarding planning the timing of pregnancy.

Physiology

The ability to become pregnant, bear and give birth to a child is a key feature of the female body. And for it to be realized, a healthy reproductive system is necessary. And it all starts with the menstrual cycle - regular structural and functional changes in the genitals. Any processes in the uterus are the result of regulatory changes in the pituitary-ovarian system. Gonadotropic hormones are produced in the brain, which activate the restructuring of the ovaries. And those, in turn, initiate transformations in the functional layer of the endometrium.

Every woman who has crossed puberty knows what menstruation is. In the medical aspect, this is the detachment (desquamation) of the surface layer of the endometrium. Their end marks the beginning of the first phase of the cycle. It takes place under the leadership of the pituitary follicle-stimulating hormone, the name of which speaks for itself. It ensures the maturation of germinal vesicles with eggs. The cells of the follicles themselves synthesize estrogens that stimulate the proliferation of the endometrium, that is, its recovery after menstruation.

In the middle of the cycle, there is an important stage necessary for conception. It's about ovulation. This is a process that is a rupture of the dominant follicle and the release of an egg from it. Without ovulation, fertilization becomes impossible because the female gamete never meets the sperm. But under normal conditions, a new structure is formed in place of the bursting follicle - the corpus luteum. It synthesizes progesterone, which is responsible for preparing the endometrium for zygote implantation. Under the influence of the hormone, the uterine mucosa undergoes a secretory transformation.

Timing

When planning the process of conception, it is necessary to take into account some important factors. Women who want to get pregnant should be aware of the time frame for the course of physiological processes. Normally they look like this:

The menstrual cycle lasts from 21 to 35 days.
Ovulation occurs on days 11–15.
The egg is viable for no more than 24 hours.
Spermatozoa are active from 3 days to a week.

Such variability in indicators is due to the individual characteristics of the organism. But on the basis of averaged data, it is possible to calculate the most favorable days for conception. So, it is known that it is best to get pregnant if sexual intercourse took place immediately at the time of ovulation, as well as for three days before or after it.

With this in mind, many women are protected from unwanted pregnancies. This method of contraception is called calendar. But it is suitable only for those who have a regular cycle and an average of 28 days. Then it is possible to calculate a favorable period on the basis of observations with a fairly high accuracy. Otherwise, errors are likely, and sometimes quite serious. Errors are also found in those who, on the basis of calculations, are trying to understand whether conception is possible after menstruation.

By calculating the time of ovulation according to the calendar, you can find out at what time pregnancy is most likely during a normal cycle.

Pregnancy after menstruation

Given the normal course of the menstrual cycle, it is safe to say that conception immediately after menstruation is impossible. Follicles are just beginning to mature in the ovaries, and the endometrium has not yet had time to recover in the uterus, not to mention its preparation for implantation. But with a short time interval from the end of menstruation, pregnancy still sometimes happens. The likelihood of its occurrence increases in such cases:

Proyomenorrhea is a cycle shorter than 21 days, which brings ovulation closer.
Polymenorrhea - menstruation is longer than 7 days, which also reduces the time gap.
Irregular cycle - ovulation can occur at different periods.
Early ovulation - occurs 2-8 days after menstruation (with a reduction in the duration of the first phase).
Spontaneous ovulation of several follicles is a rather rare phenomenon, but possible.

There are also cases when a woman takes other bleeding from the genital tract, for example, contact bleeding, for menstruation. It can be after sexual intercourse, for example, with erosion or other pathology of the cervix. And if this happened simultaneously with ovulation or in lines favorable for pregnancy, then conception will also occur. But the period actually passed much earlier.

Of course, the likelihood of getting pregnant is determined by the time when sexual contact occurred. The time elapsed since the end of the month can be:

From 10 to 17 days - "fertile window" (high probability).
From 6 to 21 days - the probability is about 10%.
Before 6 and after 21 days - low probability (no more than 6%).

It must be understood that pregnancy will not occur with sexual intercourse that took place at the very beginning of the menstrual cycle, and if emergency contraception was taken within 72 hours after it. The impossibility of conceiving a child is observed with physiological amenorrhea - after childbirth, during breastfeeding, in adolescent girls before the onset of the first menstruation and at menopause - or due to the pathology of the reproductive system. But in such cases, menstruation is completely absent.

There are situations when the likelihood of pregnancy after menstruation increases. But there are situations that have the opposite effect.

Reliable Methods

In addition to the calendar method for calculating the ovulation period, there are more reliable means of determining it. They relate to the analysis of clinical, laboratory and instrumental indicators, including the following:

Measurement of basal (rectal) temperature.
Express tests for ovulation.
Ultrasound monitoring (folliculometry).

The most accurate and reliable is the ultrasound method, when you can clearly see the growing and ovulated follicle. This study is indicated as a preconception preparation (pregnancy planning), as well as in the treatment of various types of infertility. It will also indicate the degree of probability of conception after menstruation. But for this, a woman should first consult a doctor.

The question of what terms are most suitable for the onset of pregnancy worries many women. Some want to give birth to a baby and carefully prepare for this, while others do not yet want to become a mother, using contraceptives. But for each of them, the aspect of the probability of conceiving a child after menstruation is relevant. Unfortunately, there is no definite answer. The situation can develop in different ways, depending on the nature of the menstrual cycle, especially the time of ovulation, and its changes (individual or pathological). Therefore, it is better for women to consult a doctor and use reliable methods for determining favorable terms for conception.
