Pregnancy planning: calculating favorable days for conception. What days are unfavorable for the desired conception?

The topic presented is on what days can you get pregnant after menstruation, the table is relevant for many women and girls. For some, this is a solution to the problem of unplanned pregnancy; for others, it is a selection of days when conceiving a child is most likely. Such days are calculated using different methods, characterized by the complexity of the implementation and the likelihood of results. This material will examine the processes occurring in the body of women and which periods of the cycle are most favorable for conception.

I would like to draw the attention of those women who prefer to use a method involving the use of a calendar as contraception and refuse other common methods (various medications, condoms), that, in fact, there are simply no days that are absolutely safe for conception. Answering a topic that is of interest to many - on what days can you get pregnant, we can say with confidence that a woman can conceive a child on almost any day. This is explained by the fact that there are no periods with zero probability. The only clarification is that on certain days there is more or, conversely, less chance of conceiving a baby.

The safest time period with minimal chances of getting pregnant is the few days before and after your period. To calculate dangerous days, it is necessary to know exactly the duration of the cycle, and it must be stable. The highest chances of getting pregnant are on day -15 with a 28-30 day cycle. It is at this time that ovulation occurs.

However, some deviations are possible that shift the timing of ovulation and disrupt the cycle, which can be associated with many reasons:

• physical and mental stress;
• stress, nervous breakdowns;
• the presence of various types of diseases;
• use of medications.

Calculating the most favorable days is not as simple as it might seem at first glance. If you are wondering when you can get pregnant and on what days, you should first analyze your cycle over the last year/six months. It is very important to take into account that if hormonal drugs were used during the mentioned period, in this case the calculations will not be highly accurate.

Also, one should not neglect the recommendation of many gynecologists about the need to keep your own calendar, in which the necessary data will be noted. Thanks to this, you can find out about the regularity/irregularity of the cycle. Important - if the cycle is not regular, it will be quite difficult to determine the required days.

To solve this problem, you can use other methods that solve this problem. The following method will help you calculate the time to conceive if you have irregular menstruation.

• Initially, you should highlight the shortest and longest cycle for the last year.
• Subtract the number 18 from the days corresponding to the mildest cycle. The resulting number is the beginning of the most likely period for conceiving a baby.

Many women are of the opinion that after menstruation (usually the first few days) the risk of pregnancy is reduced to zero. However, this is not true and even doctors warn that you can get pregnant at any period of the cycle.

This is explained by the fact that sperm that enter a woman’s genital tract can remain viable for a long time. That is, this means that if the cycle is short, and the period of blood release itself is long, then the probability of pregnancy is as high as possible.

There are several reasons for pregnancy to occur after menstruation:

• high activity of male ejaculate;
• such a feature of the female body as the maturation of several eggs during one cycle;
• shift in the time period for the onset of ovulation. Often this “failure” is observed in young girls due to the irregularity of the cycle. In adult women, this phenomenon is caused by hormonal imbalances.

Today, there are many methods for determining the most favorable days for conception, among them not only the calendar method, but also such as testing for the onset of ovulation, determining temperature (basal), folliculometry and others.

Conception before and during menstruation: is it possible?

Please note that there is no clear answer to this question. That is, you can answer both yes and no.

• The answer is no. As many people know, the moment of ovulation is the middle of the cycle. That is, before the onset of menstruation, the egg, as a rule, dies. If ovulation occurs again or occurs after a longer period of time, the woman will not be able to get pregnant, since the hormonal levels will adjust to the new cycle.
• The answer is yes. For any healthy woman, the chance of becoming pregnant before menstruation is quite high (especially if you have irregular sex life). This is explained by the onset of ovulation outside of the plan, which can in turn be provoked by substances contained in the male ejaculate.

We also note that the possibility of conception during menstruation is also unlikely. This can be explained by an unfavorable environment for both sperm and subsequent embryo implantation due to the large amount of blood. That is, answering the question - on what days can you get pregnant, the answer in this case will be negative. However, nature is capricious and one can expect any “surprises” from it, which is confirmed by rare cases when women conceived babies during menstruation.

On what days of the cycle can you get pregnant, table

In this part we offer information that will be interesting and relevant for many women - on which days of the cycle you can get pregnant, table.

For the most correct and correct determination of the time for conception, a special table presented below comes to the aid of the female sex. To make the necessary calculation, you will first need to calculate the duration of the menstrual cycle.

Please note that for an accurate calculation, it should be taken into account that the start of the cycle is the first day of menstruation, and its end is the eve of the next one, coming after the first menstruation.

After this, the days on which ovulation occurs are calculated, that is, this, in fact, is the most favorable period for conceiving a child.

Important! As mentioned above, in case of an irregular menstrual cycle, the basis for calculation is the shortest cycle in duration over the previous 6-12 months.

Thanks to this fairly simple but effective calendar table, you can make calculations and calculate the start days of ovulation. It also doesn’t hurt to use additional methods these days for a more accurate determination: from measuring your morning basal temperature to a banal trip to a gynecologist to conduct special tests.

On what days of the cycle can you not use protection and not get pregnant?

To calculate days that are “not dangerous” for conception, the following points should be taken into account:

• the onset of ovulation (10-18 days before the start of the next menstrual cycle);
• egg viability (about 24 hours);
• viability and activity of sperm.

Based on the presented points, you can determine on which days of the cycle you can not use protection and not get pregnant. To carry out the calculation, we offer the most popular and widespread method.

This method involves determining days using a calendar. Its essence is tracking the duration of menstruation over the past six months to a year. Afterwards, the shortest and longest periods are selected and calculations are made. For example, the duration of the shortest cycle is 26 days, the longest is 31. The calculation implies that you need to subtract 18 from 26, subtract 10 from 31. The result of the calculation shows that the safest days are the first eight days from the beginning of the cycle and the remaining days after 21- th day. On other days, the risk of getting pregnant increases significantly.

Let's sum it up

We hope that the presented material, information and calculation table will help our readers learn how to correctly calculate which days you can get pregnant.

The living conditions of spouses are multifaceted and varied. There are times when it is temporarily impossible to have a child. Sometimes spouses first want to finish their studies and settle in a new place, often they have to refrain from having another child until the first-born grows up, and sometimes the desire to have a child has to be postponed until one of the spouses recovers. To prevent conception, there are many contraceptives, which, if used correctly, can be completely harmless to the body. But for this, before choosing a contraceptive, be sure to consult a doctor.

The fact is that depending on the condition of the woman’s genital organs, the presence of inflammatory processes in them, and the position of the uterus, appropriate contraceptives are prescribed. It is completely unacceptable to use such means as, for example, lubricating the cervix and its cavity with iodine to prevent pregnancy. Such lubrication leads to inflammation of the uterus and general poisoning of the woman’s body with iodine.

The simplest method of preventing pregnancy is the physiological method. Its essence lies in the fact that conception can occur only within a few days of the menstrual cycle. Fertilization occurs only if sperm meets a mature egg cell. Remembering that sperm retain the ability to fertilize in a woman’s genitals for no more than 2 days, and the egg dies after ovulation on the 3rd-4th day, it becomes clear that conception is possible on a maximum of the 6th day after ovulation. This means that if sexual intercourse occurred earlier than 2-3 days before ovulation (sperm viability time) or 6 days after it, then conception will not occur. Another difficult thing is to accurately determine the onset of ovulation. To do this, you can use a daily recording of body temperature. On the first day of ovulation, a woman's body temperature usually rises by 0.5-0.8 degrees. This increase in temperature lasts until the onset of menstruation. If a woman’s menstruation occurs after a constant number of days and an increase in temperature also occurs on a certain day, then the confidence in accurately determining the onset of ovulation is almost beyond doubt. It is more difficult if menstruation occurs at different intervals. Then it is almost impossible to use this method.

Dr. E. G. Vasilyeva proposed the following method for determining the period of ovulation and conception. Here is its calendar table:

The calendar should be used as follows: depending on the duration of the menstrual cycle, the days of the unfavorable period for conception change (i.e., days when pregnancy is unlikely to occur). The second column shows the numbers of the unfavorable period for conception, starting from the first day of menstruation, the third - the days of the most possible conception, and the fourth column - again the number of days unfavorable for conception. For example, a woman's menstrual cycle is 28 days. This means that the first 9 days after the start of menstruation are practically infertile, then 8 days are most favorable for conception, and, finally, the next 11 days before menstruation are again infertile.

The physiological method of preventing pregnancy is the most natural for both the male and female body. The traumatic influence of foreign objects in the genitals and the inhibitory influence of preliminary manipulations disappear, in addition, sperm is poured into the vagina and here part of it is absorbed into the body, and the enzymes and hormones contained in sperm have a positive effect on the woman’s body. Thus, this prevention method is an ideal method, absolutely harmless and physiological. It should be noted that this method does not provide a 100% guarantee of success in preventing pregnancy (by the way, no method provides such a guarantee), however, due to its absolute harmlessness in combination with other methods of preventing pregnancy, it can and should be used by most married couples.

In addition to the physiological method, there are mechanical and chemical contraceptives. The former mechanically block the path of sperm to the cervix, while the latter create conditions in the woman’s vagina in which sperm quickly die or lose their mobility.

The most common mechanical device is the male condom. This is a thin rubber bag that is placed on the erect penis before sexual intercourse. Sperm is poured into it during ejaculation. The condom is not put on the penis all the way; there must be room left for sperm at the blind end, otherwise the condom may break. Before putting a condom on the head of the penis, it should be lubricated with boric petroleum jelly; They also need to lubricate the condom on top. Using a condom is the most effective method of preventing pregnancy.

Women most often use the Kafka cap, which is placed on the cervix. It is selected depending on the position of the uterus, the size and shape of its cervix. The doctor does this. As a rule, the doctor also puts it on and takes it off.

A rubber cap (CR) is inserted into the vagina and forms a septum in front of the cervix. The woman inserts this cap into the vagina herself for 2-3 days, after which it is removed and disinfected. A doctor or experienced paramedic teaches a woman how to insert a rubber cap.

The most common chemical contraceptives are various tablets, pastes, pellets, and tampons, which are sold in pharmacies.

A method such as douching and rinsing the vagina after sexual intercourse also has a good effect in preventing pregnancy. To do this, use warm water (36-38 degrees), in a liter of which two teaspoons of boric acid or two teaspoons of table vinegar are dissolved. Douching can also be done with a solution of 1:10,000.

Sometimes you can hear that the use of contraceptives with manipulations preceding sexual intercourse discourages spouses. This point of view does not stand up to criticism. If spouses love each other, if the husband sincerely cares about his wife’s health, then preparation for sexual intercourse will never affect the spouses’ feelings for each other. In addition, you can always choose contraceptives that are most suitable for the individual abilities of the spouses. It will be much worse if a woman becomes pregnant and has to resort to an abortion, because there is never any certainty that this operation will not lead to infertility, and if the spouses do not yet have children, then to an unhappy family life.

In addition to the days when the female body is capable or incapable of conceiving, there are also periods during which it is better to abstain from unprotected sexual intercourse, and especially the possible conception of a child. Remember that a successful pregnancy is just the beginning of a long journey. After all, your task is to bear and give birth to a healthy, healthy and strong baby. And this depends entirely on how the parents felt during the period of conception and some time after pregnancy. First of all, of course, you should think about the health of the expectant mother. If a woman is under severe stress, moral or physical exhaustion, takes any strong medications or smokes, it is better to refuse pregnancy for now. You should not try to conceive a child while under the influence of alcohol or drugs - the consequences can be very disastrous.

But you shouldn’t think that only the expectant mother should take care of her own health. You should think about it too. For example, smoking sharply reduces the number of viable sperm in the seminal fluid, and this leads to a decrease in the chances of fertilization. Affects semen production. If a man eats spicy, fatty or heavy food, the result is unlikely to be positive. By the way, long-term stress or illness has an extremely unfavorable effect on male fertility, so take care of your health and refrain from unprotected contacts until complete recovery.

Of course, everything cannot be foreseen. However, if you know for sure that in the coming months you will have serious work associated with constant stress or a tiring move or business trip to a region with a different climate, it is better to refuse planning a pregnancy for now. The first is especially difficult and debilitating for a woman; in addition, it is during this period that all the vital organs and systems of the embryo are formed. Agree, if you experience additional emotional, psychological and, possibly, physical stress at this time, this will not have a positive effect on your pregnancy. No matter how much you want a child, it is better to be far-sighted and think about the possible consequences. Take care of your health and postpone pregnancy for a calmer period of life.

Unfavorable days for conception can be called those days when conception is not possible for biological reasons or the body of the future parents is not prepared for it.

Preparing the body for conception and bearing a child

In order for conception to be successful and bearing a child to have minimal negative consequences for the body, it is recommended to follow a few basic points:

1. Exclude all(smoking, drinking alcohol (even in minimal quantities), contact a narcologist if necessary) at least six months in advance, and preferably earlier;
2. Follow basic recommendations for maintaining a healthy lifestyle(this includes healthy and nutritious, moderate dosed physical activity, walks in the fresh air, etc.);
3. Take preventative examination by your obstetrician-gynecologist in order to be sure that there are no contraindications for pregnancy. If diseases are detected, start treatment in a timely manner;
4. It is mandatory to undergo sexually transmitted infections (chlamydia, ureaplasma, mycoplasma, HIV, syphilis and others), as well as TORCH infections (toxoplasmosis, rubella, cytomegalovirus and herpes). If a woman has never had rubella in her life (and is not vaccinated against it), she should get the vaccine at least six months in advance. If a woman often suffers from exacerbation of herpes infection, it is necessary to carry out a long course of treatment against this viral disease in order to avoid the manifestation of the disease during pregnancy;
5. Subject to availability chronic diseases(diabetes mellitus, arterial hypertension, bronchial asthma, chronic sinusitis, chronic varicose veins of the lower extremities, tonsillitis, chronic caries, etc.) necessary before a planned pregnancy contact your doctor to adjust your treatment(long-term remission and good control of the disease are necessary).

   important It is important to remember that chronic illness significantly reduces the body’s regenerative reserves, which will be so necessary during pregnancy. Consult with your attending physician about the possibility of becoming pregnant and about measures to prepare for bearing a child with this disease;

6. If a woman is taking any medications for a chronic disease, she should check whether they have a negative effect on the fetus. If they are not recommended during pregnancy, consult your doctor about what you can replace them with;
7. Start taking(vitamin B 9) six months before the planned pregnancy (it is believed that systematic use of vitamin B 9 in a dosage of 400 mcg daily sharply reduces the likelihood of various malformations of the nervous system developing in the child);
8. Necessary pay attention to your own weight. The presence of excess body weight can seriously complicate the course of pregnancy (the body has fewer reserves), and at the same time is considered a risk factor for the development of certain diseases in the unborn baby (diabetes, etc.). To determine normal weight values, the Body Mass Index (BMI) is currently used in medical practice, which is calculated by dividing body weight (in kg) by the square of height (in m 2): BMI = body weight / height (m) * height ( m). The value in such cases should not be less than 18.5 kg/m2 (otherwise there is underweight) and more than 25 kg/m2 (otherwise there is overweight and obesity);
9. Take preventative dental examination and, if necessary, treat your teeth before pregnancy.

additionally All these provisions also apply to men, because a healthy father guarantees 50% of the health of his future son or daughter.

Calculating unfavorable days

Occurs within 24-48 hours after (the release of the egg from the ovary). With a regular menstrual cycle (for example, lasting 28 days), the maturation of the egg and its release into the uterus occurs on the 14th day. If the cycle is shorter or longer, ovulation usually occurs in the middle of the cycle.

It should be taken into account that male reproductive cells - sperm - retain the ability to fertilize an egg for several days after sexual intercourse (an average of 3-5 days), which can be considered 5 days before ovulation and 2 days after it. Hence, other days are unfavorable, namely:

1. Days during menstruation;
2. The first days after it (with a cycle of more than 28 days);
3. From the third day after ovulation until menstruation.

If it is not regular and ovulation occurs at different times or does not occur at all, it is difficult to plan conception. In such cases, you need to consult an obstetrician-gynecologist and use additional methods (ovulation tests, and others) to determine unfavorable days.

Other unfavorable days for conception

There are also days on which conception is possible, but it is better to prevent it by using contraceptive methods (condoms, spermicide suppositories).

information These are the days when future parents are intoxicated, take any substances or medications that have a bad effect on the fetus, are sick or have a cold.

Not every couple is able to conceive a child. within a few months. In such cases, almost everything matters: from the psychological compatibility of both spouses to viral infections suffered in early childhood.

You should not turn to just calculating favorable and unfavorable days for, because this is a process that you just need to enjoy. Listen to your body, and it will tell you the best days for your baby. What could be better than making love with the person from whom you want a child!

What is conceiving a child and how it happens

Biologists and luminaries of medical science have been studying the process of the birth of a new organism from two parent cells for centuries, but the question of how conception occurs is still not fully resolved.

- this is a combination of a sperm and an oocyte, merging into a zygote, which, continuing to divide, becomes an embryo, then a fetus, and finally - a small new creature that has come to the planet. Everything is simple - but there are still so many secrets here.

• What is conception
• Favorable and unfavorable day for conception
• Incompatibility of partners is the reason for the absence of pregnancy
• Stimulation for conceiving a child
• IVF conception - what is it?
• Pregnancy has occurred: what next?

What is conception

Conceiving a child is not an instant process. Sexual intercourse alone is not enough to conceive a child.

This happens in several stages, which are repeated in almost every menstrual cycle:

• Maturation of the oocyte, which lasts for 14 days.
• The release of the “ready” egg into the abdominal cavity is ovulation.

• Capture of the egg by the villi of the fallopian tube and penetration of the oocyte into the infundibulum of the tube.
• Penetration of sperm into the tubes. Passing the way from the vagina, through the cervix, the uterine cavity, some of the sperm die.

• Meeting with the egg.
• Dissolution of the oocyte shell by sperm enzymes, penetration of the “fastest” one inside.
• The fusion of the male and female “halves” is the formation of a dividing zygote.
• Promotion of the zygote through the tubes into the uterus.

At any stage, a failure may occur and conception will not take place.

To successfully conceive a child, several factors must coincide:

• successful ovulation;
• , without genetic defects egg;
• presence of active sperm.

After sexual intercourse, if a sperm meets an egg, the woman does not have any special sensations. The first week is not yet pregnancy. Knowing what happens after conception day by day, you can predict when a woman will feel the first symptoms of pregnancy.

The merging process takes place within 2-36 hours. The journey of the future embryo through the tubes continues for 6-7 days. Afterwards it enters the uterus, where. At this time, some note the first sign that allows them to understand whether fertilization has occurred. It is called "implantation bleeding."

A woman notices a drop of blood on her underwear or a pink mark on toilet paper (this does not happen to everyone). Her first thought: “My period has come - early!” But this is not menstruation, but evidence of implantation of the fertilized egg into the wall of the uterus - implantation. Small vessels are damaged - hence the admixture of blood. Pregnancy has begun.

What is an unfavorable day for conception?

Women know: there are days when the probability of a new life being born is almost zero. Unfavorable days for conception (safe) are considered to be 3-4 days immediately after menstruation. We take into account the week after the start of menstruation plus 3 - 4 days. This is the period of preparation of the female body for conception in the current cycle. The hormonal level changes, the maturation of follicles begins, of which by the time of ovulation the dominant one will be determined - the vesicle with the future egg. Conceiving a child is not yet possible.

With a cycle of 28 days by 14 (2 weeks from the expected end of the cycle): rupture of the follicle, release of the egg. Women are interested in how to understand that ovulation is near. A sure sign is a decrease in basal temperature. Sometimes my stomach feels weak.

You often feel unwell on this day, but ovulation (and the day after) is the most favorable moment for conception. The previous 2 days are considered suitable. Sperm can live in the tubes for 3-4 days; on the fifth day they die.

Conception window in the women's calendar

The “window of conception in the female calendar” (also known as “”) is approximately 4 days in the middle of each cycle. These are the previously discussed 3 days before ovulation plus a day after it. At this time, the uterus is ready for implantation.

If fertilization of the egg occurs after the window of conception has closed, the embryo will not be able to implant in the uterus. After this period, conception is impossible: the sperm die and the egg becomes unviable. The body prepares it to be released with menstrual blood.

Incompatibility during conception is the reason for the absence of pregnancy. Sometimes partners try to conceive a child for a long time, catching every ovulation - to no avail. The reason in some cases is the incompatibility of partners. How long to wait before going to the doctors is up to each couple to decide for themselves. The recommended period for seeking help is 6 months from the start of conscious and regular attempts to become pregnant. Doctors identify the following discrepancy:

• by gene combinations;
• immunological problems.

The biggest mystery is immunological incompatibility: the antigen proteins of a woman’s body, mistaking “strangers” (spermatozoa) from a man for dangerously degenerated own cells and destroy them.

Today, most problems can be corrected.

Ovulation induction increases the chances of success for those planning a child. It is used for a number of other gynecological problems. A preliminary examination is carried out:

• blood sampling for hormonal testing;
• checking the patency of pipes;
• Ultrasound of the uterus, ovaries;
• spermogram analysis.

Only qualified doctors know how to understand that stimulation will help in a particular case. Stimulation for conception is carried out either with clostilbegit (orally) or with gonadotropins (injection). The meaning is to help the maturing follicle, “spur”, forcing its development. What happens next is the same as during normal, natural ovulation: the egg leaves the follicle and “settles” in the tube. When stimulated (depending on the protocol design), several eggs mature. After sex, sperm quickly rush to the ready egg, one gets inside. A zygote is formed. Next, the zygote divides in the woman’s body, and after a week the embryo is attached. Utrozhestan and Duphaston are used to support pregnancy.

IVF conception - what is it?

It’s the third week after PA (or replanting) - a home test should already show 2 stripes. During the examination, the gynecologist will see an enlargement of the uterus and note the cyanosis of the cervix. In the first days of pregnancy, a woman can learn about upcoming changes by her own feelings: something has changed in her, but she does not always realize what exactly. Still too fragile, unreliable.

If you are planning to conceive a child, remember that the first days and weeks are the most crucial time. You need to give your body the opportunity to get used to the new “resident”, and to do this, calm down, eat well, walk a lot, and get a lot of positive emotions. Then everything will go as it should. Help nature accomplish its great secret - the secret of the birth of new life!
