Is there a chance of getting pregnant after ovulation? The birth of a new life: is it possible to get pregnant after ovulation?

For young people who have made a serious decision to become parents, a rather difficult period begins - the period of conceiving a baby.

It is not always possible to achieve the desired two stripes on the test the first time. IN this issue you can’t do without such a concept as . It is she who controls and coordinates the meeting of the egg with the sperm.

What is ovulation?

From a medical point of view, ovulation is the process when a mature follicle ruptures, allowing the egg to be released from the ovary.

At the first stage under the influence of a certain hormone in the body, the follicle grows until ovulation.

On next stage — Once the follicle reaches the required size, the content of the hormone in the body increases, under the influence of which the egg matures.

Final stage- when the egg is released and comes out of the ovary, it is called ovulation. Peak activity of the female egg occurs within 48 hours.

Then comes stage corpus luteum - a period when pregnancy is impossible. At this moment the egg is in the fallopian tube, and this is where, as a rule, fateful meeting with sperm.

If fertilization has occurred, a zygote is formed, which, within approximately ten days, enters the uterus, where it attaches to the wall of the uterus. This final stage at the onset of pregnancy.

If conception does not occur, the destruction of the egg occurs within 24 hours.

A situation where ovulation occurs regularly, but pregnancy cannot be expected - quite natural. Otherwise, pregnancy would occur after each egg matures.

However, if conception does not occur for a long time, it is better not to postpone a visit to the doctor and certain examinations.

What is the probability of pregnancy during ovulation?

Numerous medical research proved that the most high probability of conception during ovulation. Thus, by accurately knowing the day of ovulation, the chances of getting pregnant are one in three or 33%.

Trying to conceive a baby before the day of ovulation can also be successful, but with a lower percentage. The probability of pregnancy one day before ovulation is 31%, two days – 27%, three days – 16%. This is explained by the fact that after intimacy sperm still within five days may remain active, which can lead to pregnancy.

It is possible to get pregnant more days before ovulation, but the chance of success is much less. It is minimal if there are six days before ovulation.

Methods for determining ovulation

First signs of pregnancy after ovulation

Undoubtedly the most in an exact way To determine whether pregnancy has occurred is to visit a doctor.

However, there are others indirect signs conception.

• Menstruation does not start at due date. This is one of the most basic signs, especially if a woman has an accurate and constant menstrual cycle.
• Magnification and painful sensations in the chest
• Frequent urination.
• Change in taste preferences.
• Fatigue, drowsiness, nausea.

Every woman can feel indirect signs of pregnancy at different dates pregnancy. One woman will feel that she is pregnant within a few days after fertilization. Another woman - only after a visit to the doctor and a delay menstrual cycle.

Exists a number of precise signs pregnancy.

• Examination by a gynecologist.
• Listening to the baby's heartbeat.
• Ultrasound examination.
• Blood test for hCG level(hormone indicating pregnancy).

Is pregnancy possible after ovulation?

According to experts, the answer to the question “When does pregnancy occur after ovulation?” will negative. In medicine there is a term - “absolute infertility”.

Ovulation is a kind of milestone in the menstrual cycle, after which the corpus luteum stage begins; during this period, conception is impossible.

It is advisable to use a pregnancy test only from the first day of the delay. Without waiting for the expected date, many closely monitor changes in the body, including vaginal secretions, in order to recognize the onset of pregnancy as early as possible. In this article, we will thoroughly understand the question of whether the discharge after ovulation has clear differences if conception occurred or did not occur.

What should the discharge be like immediately after conception: before the implantation of the fertilized egg?

Discharge during conception is no different from normal cervical mucus during the fertile period. At this time, estrogen dominates, which provokes thinner and more abundant mucus from the vagina, similar to snot or egg white, which increases the likelihood of getting pregnant (see photo). May also be observed.

Unpleasant smell, heterogeneous consistency, the presence of incomprehensible lumps, pus - this is a direct indication of problems with the reproductive system. It is especially important to urgently go to the hospital for girls who suspect the possibility of pregnancy. The presence of infection, fungus and any other pathology can prevent the fertilized egg from gaining a foothold in the uterine cavity, cause spontaneous abortion, or cause harm already during the development of pregnancy.

Discharge during fertilization of an egg: changes by day

The parameters of discharge with conception change as follows:

1st day. Saved liquid state, abundant amount, transparent or whitish tint (male and female reproductive cells merge).

2nd day. The sex hormone progesterone begins to dominate in female body. In some women, the cervical fluid thickens instantly, while others still notice the ovulation secretion on daily pads.

3rd day. The zygote has already formed and intensive cell division continues. The presence of blood can no longer be associated with follicle rupture, but for implantation ovum it is too early. Most often, scant ones are observed.

4th day. The embryo enters the tubes, and it already contains as many as 16 cells. There is no significant effect on vaginal secretion, the situation continues for the third day.

From the 5th to the 7th day. During this period, the fertilized egg reaches the uterus, where it will be decided whether pregnancy will occur or not. A positive result is the fixation of the embryo in the mucous layer of the uterus (this may occur later).

What does the color of discharge after conception and before menstruation indicate?

You can be guided by the shade of the discharge to mark the absence of pregnancy or the beginning of the first month of the gestation period.

White discharge after conception and in the second half of the cycle

Mucus of this shade should have a uniform consistency and not cause discomfort in the form of itching and burning. This substance cannot indicate that pregnancy has occurred, since it has no significant differences.

Yellow

Such traces on panty liners are allowed during the luteal phase in the absence of pregnancy, but they should not be saturated (yellowish or). are not a sign of conception, but the likelihood of fertilization occurring still exists.

Transparent secret

After ovulation, vaginal mucus should become thicker and take on a whitish tint. But a small amount clear liquid acceptable at any period of the cycle.

Red, brown, pink

Mucus of this color is normal if it is caused by the fertile period and. In all other situations, you need to check with a doctor. In the first case, we are talking about rupture of the follicle and damage to the blood vessels, and in the second, about fertilization. They are distinguished by the time of occurrence and intensity. The first option is that they are scanty in nature (a brown drop on the pad) and are accompanied by aching pain in the lower abdomen. Find out about the characteristics of the second option below.

What is implantation bleeding?

Bloody discharge after conception, indicating the attachment of the fertilized egg, will not appear before the fifth or sixth day from the moment of fertilization.

This is the minimum required for an embryo to implant into the wall of the uterus. Thus, you should expect the appearance of such discharge a week after ovulation or a week before your period, which will indicate pregnancy.

You may notice a small amount of mucus with clots or drops of blood on your panty liner or underwear (see photo). The nature of secretion may vary depending on the ratio of vaginal fluid and blood streaks. The intensity exceeds the discharge during ovulation. The following shades are allowed:

• red;
• pale pink;
• brownish;
• light yellow.

It is important to estimate the duration and volume bleeding after ovulation

1. Conception has occurred. The duration of implantation bleeding ranges from several hours to two or three days. Moreover, there should not be a lot of vaginal fluid.
2. Conception did not occur. The discharge begins as a spot and progresses to full menstruation.
3. Sign of pathology. The pad gets wet in an hour or less, so you can’t put off going to the hospital, because there is a suspicion of bleeding.

According to reviews from pregnant women, most often implantation discharge after fertilization appears 6-12 days after ovulation. Moreover, gynecologists claim that most patients did not encounter this phenomenon at all or did not pay attention to it.

Is pregnancy possible if there is no secretion?

The absence of discharge after ovulation is a type of norm for the monthly cycle. The reason lies in individual characteristics body, as well as the state of hormonal levels. After the fertile phase, progesterone levels increase, and this hormone creates Not favorable conditions for the movement of sperm, when the mucous plug of the cervical canal is the least permeable.

But in most cases, there is still a sticky or sticky secretion, which becomes watery before menstruation. To determine pregnancy, it is better to check close attention for changes in the body that indicate it:

• fatigue;
• soreness of the mammary glands;
• dizziness;
• change in attitude towards food;
• increased drowsiness;
• mood swings;
• abdominal pain (can pull the lower back).

How can you tell by the discharge if fertilization has failed?

The main difficulty is that the nature of the discharge after ovulation, if conception does not occur, is very similar to the secretion of women during early pregnancy, that is, until the blastocyst attaches to the wall of the uterus. From the moment of the ovulatory period until menstruation, the secretion is in the form of chicken protein or copious mucus should change to a sticky or sticky liquid with a thicker consistency. Shortly before the end of the menstrual cycle cervical mucus practically disappears, appearing a few days before menstruation. The most striking sign can be considered the above-described implantation bleeding, but due to the fact that it is quite a rare occurrence, it is not worth drawing conclusions based on its absence.

The right thing to do is to appreciate your feelings and wait about a week. If there is no blood in the vaginal secretion, no aching pain and cramps in the lower abdomen, conception is unlikely, but not excluded. For greater confidence, you can do a test based on the immunochromatographic method for determining the level of human chorionic gonadotropin in the urine (ultrasensitive 7 days after ovulation).

What does it mean about pathology?

All the secretions causing redness genital organs, irritation, burning, do not exclude pregnancy, but also the risk of developing inflammation and other pathological disorders.

The following cervical mucus indicates problems in the reproductive system:

• curdled lumps, itching, burning (thrush);
• dark brown (polycystic ovary syndrome, severe inflammation);
• deep yellow, green, (infection).

This is just a small list possible diseases. To make a more accurate diagnosis, it is necessary to undergo diagnostics and tests.

It happens that brown or red discharge after ovulation torments women with cervical erosion when the affected area is systematically damaged.

or before expected menstrual bleeding cannot 100% guarantee the success of conception.

Ovulation is the process of the release of a mature egg from a woman’s ovary. This day occupies the middle position in the body's menstrual cycle. The process takes only 15 minutes.

How long does it take for conception to occur and how many days does it take for pregnancy to occur? Immediately after ovulation, pregnancy is most likely to occur. The egg lives on average 24 hours, and after this time, if it fails to meet an active sperm, it is eliminated.

What are the chances? The chances of getting pregnant are very high within 24 - 36, and in exceptional cases 48 hours after ovulation. Is it possible to conceive a baby if several days have already passed?

Pregnancy AFTER OVULATION (what is the likelihood):

How does the process of fertilization of an egg occur on the first day?

The largest follicle in the ovary breaks its wall and is attracted by the villi of the fallopian tube. It begins to move into the uterine cavity. Here, a meeting between sperm and oocyte may occur in the tube. In this case, they say that fertilization occurs.

This whole process is “sponsored” by special hormones: FGS (follicle-stimulating hormone), progesterone and testosterone.

Each egg creates a cavity with a unique set of chromosomes, which must merge with the paternal ones, then the “project” of the future baby can be considered completed and fully equipped.

When does the process of conceiving a child begin?

The process of conception occurs approximately after the 12th hour of ovulation. Implantation retraction is the settling of the fertilized egg in the uterine cavity. Literally implantation is translated as implantation.

How do you know if conception has occurred? During this phenomenon, the body temperature rises due to a decrease in the level of the hormone progesterone in the blood of an already pregnant woman. It occurs approximately 5 days after ovulation or 19 days of the menstrual cycle with its classic duration of 28 days.

With this phenomenon, the body temperature drops sharply, the condition lasts for 24 hours, and then rises again. On this day it is approximately 36.8 g. – 37 gr. Although in the post-ovulation period it is supposed to be 37.2-37.5 g. By measuring her body temperature every day, a woman can find out about pregnancy earlier than the test can recognize it.

After how long or on what day does the embryo attach to the uterus?

Fertilized egg - the embryo is already fixed in the uterine cavity 6-7 days after ovulation within 40 hours. Thanks to nutrients, which are contained in the uterine mucosa, the embryo can grow and develop. If not, he dies.

How does attachment and formation of the fetus occur?

After the sperm reaches the egg, it penetrates into it. Cores female cell and male merge together, a zygote is formed (one single whole cell). Then every day a hundred cells begin to be added as a result of division. The future baby is rapidly growing in size.

During the first 20 weeks, the placenta begins to form inside the uterus, as if enveloping the unborn child with a warm blanket, providing protection and nutrition to the fetus.

The embryo produces enzymes that can dissolve a section of the uterine mucosa and integrate into it. Wherein a woman may detect small bloody issues on linen. This does not indicate anything terrible. Just an embryo, embedding itself in the wall of the uterus, tearing apart blood vessels and causes this effect.

This is the most dangerous period throughout the entire pregnancy, which decides whether or not the child will be born or not.

How to increase the chances that already exist?

We invite you to watch a video about factors that increase your chances of getting pregnant:

The day of ovulation depends on the length of a woman’s menstrual cycle (28-32 days) and falls in its middle. You can get pregnant only in the first two days after the release of the egg into the fallopian tube, neither a day earlier nor a day later. Although attempts to conceive should not be dated to this day, but 2 to 3 days before. This is due to the fact that sperm can remain viable in a woman’s body for 5 days.

If the sex of the unborn child is unimportant, it is necessary to adhere to this scheme 100%. If conception does not occur during the ovulation period, the egg is removed from the woman’s body along with menstrual blood. Pregnancy does not occur. Any woman should seriously monitor her health and remember to visit the gynecologist’s office at least once every six months.

Collapse

U healthy women Ovulation occurs regularly. How to find out if conception occurred after ovulation? Neither a pregnancy test nor an ultrasound will give any result immediately after ovulation because hCG is not produced during the pre-implantation period. Once the fertilized egg attaches to the uterine wall and hormone secretion begins, a test can be done. Until this moment, a woman can record the initial signs of pregnancy, which are not always objective.

Favorable period for conception

Is it possible to get pregnant before or after ovulation? Maximum probability conception occurs on the day of ovulation. Favorable time after it is calculated in hours and averages less than a day. This is explained by the fact that the oocyte lives only 12-24 hours. The potentially dangerous period is about 8 days (7 days before the oocyte is released and 1 day after it), since sperm live from 2 to 7 days. That is, they can penetrate the tubes even before ovulation and wait for the egg there. In this case, conception occurs on the day the oocyte is released.

Ovulation

To calculate ovulation, you need to divide the average cycle length by two; the error is three days in both directions. This method is not very accurate because ovulation may occur earlier or later than the middle of the cycle. A test for LH (luteinizing hormone) in the urine can accurately determine the yield of the oocyte. An increase in LH levels indicates approaching ovulation. The test allows you to find out about ovulation a day before its onset with an accuracy of 99%.

Signs of pregnancy

They will help you understand that conception has occurred specific signs, signaling a change in hormonal levels. Preimplantation symptoms of conception and fertilization are not reliable, but sometimes accurately indicate the presence of pregnancy.

Bloody issues

Minor spotting that appears after ovulation may indicate conception; this is implantation bleeding that accompanies the implantation of the embryo into the uterine wall. This discharge is often mistaken for the beginning of menstruation. But we cannot ignore the bleeding that appears repeatedly throughout the day or more. This could mean an impending miscarriage, a condition that requires medical attention.

Bloating

Long before toxicosis occurs, a woman may complain of increased gas formation and bloating. These symptoms can be considered a sign of pregnancy if they occur towards the end of the cycle.

Some report intolerance certain products and smells, unusual food preferences. These phenomena disappear over time, but having become pregnant for the second time, the woman already clearly knows what the occurrence of these symptoms indicates.

Abdominal cramps

Also, many women indicate such signs of pregnancy as heaviness in the lower abdomen and cramps, sometimes tingling and nagging pain. These symptoms may also indicate increased tone uterus, so if they continue for a week, then you need to consult a specialist.

Changes in the mammary glands

Soreness, enlargement and engorgement of the breast, enlargement and darkening of the areolas are the main signs that conception has occurred. These phenomena occur before menstruation, but at the beginning of pregnancy they are more pronounced and can last longer. A woman may also notice light discharge from the nipples, the mammary glands begin to produce colostrum.

High basal temperature

If fertilization has occurred, then the elevated basal temperature should remain throughout the second half of the cycle. Sometimes the sensations when an egg is released are mistaken for the onset of fertilization, since the symptoms that occur during ovulation are similar to signs of conception. It is safer not to rely on subjective feelings, but to wait until the 10th day of the expected pregnancy and conduct a test.

After fertilization, basal temperature rises. If the thermometer shows 37 degrees, this allows us to conclude that possible pregnancy even before the delay. After ovulation and fertilization occur, increased production of progesterone begins. It is he who gives the increase to 37 degrees.

Normal temperature after fertilization is an unfavorable prognostic sign and indicates a lack of progesterone. This condition poses a risk of miscarriage and requires treatment.

Fatigue

TO initial signs pregnancy includes increased fatigue, sleepy state And constant feeling ailments caused by hormonal changes. After ovulation and conception, the body adapts to its new state and provides protection to the embryo. If pregnancy occurs after ovulation, immunity automatically decreases to maternal organism does not reject the embryo, which he perceives as a foreign body.

Irritability
An informative sign of pregnancy is severe irritability And emotional lability, which is also a reaction to hormonal changes occurring in the body. If a woman is nervous and irritated for any reason, then this may indicate that conception has occurred.

Increased PMS symptoms

Unpleasant sensations after ovulation and conception may resemble discomfort before the onset of menstruation. They are evidence of the onset of pregnancy. Severe and prolonged pain may indicate abnormal attachment of the egg, so if it continues for more than 14 days, then you should visit a doctor.

Stomach ache

In the first days after conception, mild pain in the sacrum and discomfort in the lower abdomen sometimes occur. More severe pain occurs with a threatened miscarriage or ectopic implantation, in addition to bleeding.

Gastrointestinal dysfunction

Sometimes the first signs of conception after ovulation are associated with dysfunction of the gastrointestinal tract. If more than a week has passed since the estimated moment of conception, the woman may experience the following symptoms:

• nausea, vomiting;
• heartburn;
• increased gas formation;
• heaviness in the stomach;
• perversion of taste.

These symptoms occur when conception occurs after ovulation and the egg is implanted into the uterus. Before it happens hormonal background remains at the same level and any changes in gastrointestinal tract functions are not informative.

Cystitis

The early stages of fetal development in many women are accompanied by inflammation Bladder. The reason for this phenomenon is not so much that the growing uterus puts pressure on the bladder (it is still no larger than chicken egg), how many in hormonal changes body. weakens immune defense As a result, the infection penetrates the urinary organs and cystitis develops. Problems of this nature can haunt a woman throughout her pregnancy. Treatment is carried out antibacterial drugs who don't have negative influence for the fruit.

Signs of conception by day

For the fusion of gametes, a full-fledged egg must be released from the follicle. A mature cell is capable of fertilization and subsequent division. On what day after ovulation does conception and fertilization occur? Most often, on the same day, the life of the egg is short - about 12-24 hours.

First day

Sperm must travel a certain distance to enter the fallopian tube, where the egg awaits them. This process takes about 2-6 hours. After the struggle, the sperm penetrates inside and fertilization occurs. In most cases, there are no signs of conception after ovulation before implantation. A woman does not feel anything on the 1st day of pregnancy.
Second day
The immune system perceives the fertilized egg as a foreign body, therefore, on the 2nd day of pregnancy, the production of antibodies begins, the so-called immune attack. From this future mom feels tired and overwhelmed. In addition, on the second day, changes in taste preferences, bloating and nausea may occur, as well as signs of egg fertilization such as engorgement and tenderness of the mammary glands.

The third day

The first few days, including the 3rd day of embryo development, occur in the fallopian tube. A woman may lose her appetite, experience nausea and dizziness. Starting from the third day, the woman’s body begins to rebuild and prepare for implantation.

Fourth day

On the 4th day after the fusion of gametes, thanks to the peristalsis of the tubes, the embryo enters the uterus. Signs of pregnancy on this day: increased gas formation, bloating. Feeling foreign body in a stomach.

Fifth day

Implantation means the process of attachment of the embryo to the uterine mucosa, which occurs from 5 to 9 days from the moment of fertilization and lasts about 40 hours. If the embryo does not move into the uterine cavity, but continues to develop in the tube, then ectopic pregnancy. On the 5th day after the fusion of gametes, the temperature may rise, dizziness and chills may occur. A woman feels like she has a cold.

Sixth day

On day 6 there is an increase basal temperature, which must be measured without getting out of bed in the morning. A nagging pain is felt in the lower abdomen, as before the onset of menstruation.

Seventh day

Signs of pregnancy on day 7 are: slight light brown or pink discharge. They can occur between the fifth and seventh day after gamete fusion, corresponding to embryo implantation.

Eighth day

Start of the second week embryonic development corresponds to the first critical period of formation. During this period of time, teratogenic factors lead to the death of the embryo. But if he survives, then he does not have any developmental defects. On the 8th day there is a feeling constant fatigue, headaches and dizziness. The expectant mother looks pale.

Ninth day

The embryo, which is at the stage of crushing, reaches the uterus and begins to sink into the mucous membrane. This sometimes causes minor implantation bleeding. Until day 9, signs of pregnancy are very scant and similar. Due to the fact that hormonal levels begin to change, the expectant mother feels extreme fatigue, therefore, on the 9th day after the fusion of gametes, the woman feels drowsy.

Tenth day

On the 10th day, the embryo is finally implanted into the uterine mucosa. Now you can determine the presence of gonadotropic hormone in the blood. Biochemical analysis blood test, which can be done from this day on, objectively confirms the onset of pregnancy. After day 10, you can use a highly sensitive test.

Eleventh day

For most women, the approach of menstruation is accompanied by some characteristic sensations: mood lability, nagging pain in the back or lower back, migraines, engorgement and breast enlargement. And if on the 11th day these signs are absent, then it is possible that you should no longer wait for your period.

Twelfth day

On the 12th day of embryonic development, dyspeptic symptoms may appear: changes in taste, nausea, vomiting, and aversion to certain odors. These symptoms of fertilization occur in the vast majority of expectant mothers. At this time, the body itself can tell you what it needs for the correct formation of the fetus, so women note a change taste preferences. They may be attracted to those foods that seemed tasteless to them before pregnancy, and their previously favorite dishes may cause disgust.

Thirteenth day

Changes in mammary glands begin to occur immediately after conception, parallel to the processes occurring in the uterus. On the 13th day of pregnancy, a common sign of fertilization is discomfort in the mammary glands, and in some cases even slight discharge from them. The body is preparing for breastfeeding, the result of the changes may be darkening and swelling of the areola around the nipples.

Sixteenth day

From the 16th day of pregnancy, a neural plate is formed in the embryo, the ends of which connect and form a tube. This is how it begins nervous system. After this it is laid skeletal system embryo.

Carrying out the test

How to find out whether conception has occurred and whether pregnancy has occurred after ovulation? The accuracy of the test results depends on the timing of the test. In order for it to detect pregnancy before the onset of menstruation, you need to purchase a test with high sensitivity. Some products are able to show hCG concentrations starting from 10 mU/ml and record fertilization already on the 10th day. The second type of test is less sensitive and notes the presence of hCG only from 15-25 mU/ml, that is, after the first day of a missed period.

It often happens that conception occurs, but the test is negative. One of the reasons for this phenomenon may be non-compliance with the correct sequence of the test specified in the instructions. The objectivity of the study can also be affected by drinking excessive amounts of liquid and conducting the test in evening time, which affects the concentration of the hormone in the urine.

If the second strip is poorly visualized, it is recommended to conduct secondary testing after a few days. Sometimes hCG increases slowly, and the test will record a false negative result up to 3 weeks after the fusion of gametes. In this case, a woman can focus on subjective signs of pregnancy.

From about 12–13 years old, girls begin menstruation, which indicates readiness reproductive system reproduce offspring. The menstrual cycle is a complex phenomenon and includes a lot related processes. One of the most important things from the point of view of the possibility of getting pregnant is ovulation. Let's find out exactly how it is connected with conception and when there are the greatest chances of becoming a mother.

What is ovulation

As part of the menstrual cycle, the female body undergoes cyclic changes stimulated by the production of hormones. Thus, in one of the ovaries, thanks to follicle-stimulating hormone, a dominant follicle matures, inside which the egg is located. Approximately in the middle of the cycle, it ruptures, releasing a cell ready for fertilization, and this phenomenon is called ovulation. Afterwards the egg moves along fallopian tube towards the uterus, where favorable conditions have already been created for further implantation subject to fertilization. If conception does not occur in the current cycle, then the egg dies and, together with the exfoliating lining of the uterus, is removed through menstrual bleeding from the body.

Ovulation is the process of the release of an egg ready for fertilization from a follicle in the ovary

Ovulation and conception

Ovulation is directly related to conception, since if a mature egg does not come out of the ovary, then you will not be able to get pregnant.

When planning a replenishment, many expect to get a positive result the first time, but this is not always possible, because successful conception depends not only on the fact of having a ready egg. IN medical science It is believed that trying to have a child for one year is the norm, and only if after 12 months you cannot achieve what you want, you should contact a specialist to clarify the reasons.

At average duration In a 28-day cycle, follicle rupture occurs approximately in the middle, on days 13–15, but deviations from this figure are possible. It is not worth calculating the day of ovulation based solely on the stable order of menstruation; this rarely provides reliable information necessary for conception. The following methods are considered the most reliable:

Best days to conceive

Determining ovulation is of great importance for the success of conception, since female egg lives for a short time - from 12 to 36 hours, after which it dies and chances are this cycle it won't be anymore. So, most favorable days The following are considered for trying to get pregnant:

• the day of ovulation itself - the probability of conception reaches 34%. In this case, the sperm must be active enough to reach the target;
• 5 days before ovulation. This figure is due to the viability of sperm - in some cases they can remain active in a woman’s reproductive system for exactly 5 days. Sexual intercourse during this period has an increasing chance of producing fertilization - from 10% 5 days to 31% 1 day before ovulation;
• 1 day after ovulation. After release, a phase of rapid decline in fertility begins, as the egg dies quite quickly. There is a chance of getting pregnant during this period, but it is not too high. After 1–2 days, a period of absolute infertility begins, which lasts until the end next menstruation, and you can’t get pregnant either a few days or a week after the cell is released.

It is impossible to get pregnant without ovulation, since the main condition for conception is missing. It is important to understand that an egg may not mature every cycle; on average, a woman produces 10–11 cells capable of fertilization per year, and the remaining cycles are anovulatory.

Safe days or periods of minimal fertility

There is a method of preventing unwanted pregnancy by detecting ovulation (called calendar). It is based on calculating the day the egg is released and excluding sexual intercourse during this period. This approach is inherently really effective, since in each cycle there are safe days when there is no chance of getting pregnant at all - this is the time from the beginning of the cycle (the onset of the next menstruation) until 5 days before ovulation, and the interval from 2 days after the release of the egg to next menstruation. It's simple and logical: no living egg - no pregnancy. However, this method has its drawbacks. Thus, the timing of ovulation can shift in each cycle under the influence of a variety of reasons, and it is impossible to know exactly when the follicle will burst, and therefore to calculate the “dangerous” period before this event. The approach is effective only in a situation where the fact of ovulation is known reliably and more than a day and a half has passed.

Calendar method contraception involves calculation safe days with no chance of getting pregnant

Signs of successful conception after ovulation

When the sperm reaches its goal and fertilizes the egg, the stage of implantation begins - penetration into the prepared loose lining of the uterus and consolidation there for further division and development of the fetus. This takes some time, so immediately after intercourse during ovulation it is impossible to find out about the fact of conception, since the corresponding changes in the female body have not yet begun to occur. Pregnancy can be reliably established based on the results of a blood test taken over time at a certain interval to establish the level of human chronic gonadotropin (hCG) and according to ultrasound data.

• At the same time, there are a lot of signs that cannot be considered unambiguous, but they, especially in the aggregate, can with a high probability be evidence of a conception that has occurred:
• delay in the onset of menstruation (if the implantation of a fertilized egg into the walls of the uterus has occurred, then there will be no rejection of the lining, and therefore no menstruation);
• swelling and tenderness of the mammary glands; implantation bleeding - slight highlight
• blood in the absence of full menstruation. During implantation of the egg, the vessels in the uterine wall may be injured, which will cause short-term bleeding;
• a sharp “dip” (decrease) in the basal temperature chart 2–5 days after ovulation;
• slight malaise due to decreased immunity (this is necessary so that the embryo is not rejected);
• slight pulling sensations in the lower abdomen, warmth due to the rush of blood.

After conception. the egg moves systematically to the uterus, where it is implanted into its wall

At home, if you suspect pregnancy, you can do a test for hCG in the urine. If it is negative, do not be upset, since the sensitivity of such an express method may be insufficient in the early stages, and it is worth repeating it later.

Pregnancy tests behaved differently among my friends. For one girl, the coveted two stripes appeared on the very first day of the delay; for the second, a distinct stripe was absent for almost 10 days, until she took a blood test to detect the same hCG and found out that she was pregnant. In my case, a pale stripe positive result was noticeable 3 days before the expected period, and it was present only on 2 tests out of 4 purchased from different manufacturers.

Ovulation occurs, but pregnancy does not occur - reasons

The presence of a mature egg is one of the main conditions for conception, but far from the only one. The process of creating a new life is very complex, and its success depends on large quantity factors. If a woman ovulates, but pregnancy does not occur, this may be a consequence of the following conditions:

• hormonal imbalances. They may exist due to problems with endocrine system, due to a previous illness or nervous tension;
• inflammatory diseases in the reproductive system of both women and men;
• obstruction fallopian tubes, due to which the egg cannot reach the uterus;
• infection of the uterus;
• endometriosis - the spread of endometrial tissue outside the uterine cavity, which becomes a source of formation of adhesions, cysts, scars, inflammatory processes preventing pregnancy;
• underdevelopment of the endometrium - too thin a layer does not allow the fertilized egg to latch on and implant;
• insufficient number of healthy and motile sperm in the male ejaculate.

Gallery: reasons for the absence of pregnancy with intact ovulation

Inflammatory processes in any element of a woman’s reproductive system can prevent pregnancy. One of the common reasons for non-pregnancy during ovulation is the low activity of a man’s sperm. Endometriosis is the spread of endometrial tissue to areas outside the uterus. Obstruction of the fallopian tubes leads to the inability of fertilization and movement of the egg into the uterus.

Lack of ovulation - what to do?

In a situation where a woman has diarrhea, first of all, specialists begin to find out the causes of this condition. This may happen due to infectious disease, increased load on the psyche, hormonal imbalance, and even insufficient weight (less than 18% body fat). After identifying the source of the problem, measures are taken to eliminate it, which will be determined on an individual basis. It could be:

• reception hormonal drugs to restore balance;
• antibiotic therapy for identified infectious diseases;
• a course of drugs to stimulate ovulation;
• comprehensive measures for weight gain;
• laparoscopic surgery in case of polycystic ovary syndrome.

After successful treatment and ovulation resumes, you can start trying to have a child again.

Video: what determines the likelihood of conception

Ovulation is the release of an egg ready for fertilization and is one of the the most important conditions for conception. There is a window of maximum fertility, when the chances of sperm to fertilize an egg are maximum, and intervals when it is simply impossible to get pregnant. In any case, the same principle remains: no ovulation - no conception, so it is important to identify the reasons for non-ripening dominant follicle and eliminate them in a timely manner.
