How to count the day of conception. Online conception calendar

You're already pregnant! Congratulations! This is a wonderful state of a woman! But how can you find out when conception occurred? After all, this is simply very necessary to find out the baby’s future birthday. What do women need to know to do this?

Calculating the day of conception

To calculate the day of conception, two dates are needed. First, remember the first day of your last menstrual cycle, and second, analyze the days when you had. It is necessary to remember as early as possible; there are cases when women simply forget about such information, since their thoughts are all about the child.

Yes, we think so. The most normal period of pregnancy is 280 days from the moment of conception. In other words, 40 weeks or 10 months. Have you asked the question why 10 and not 9 months? And all because you need to count from the beginning of your last menstruation, which occurred before conception.

Did you have a question, why do gynecologists carry out calculations this way? And the answer is simple, because girls don’t really remember the last time they had sexual intercourse. There is another situation when you need to figure out which guy has become a daddy. This exists if a girl has many sexual acts with different partners.

Here's some more interesting information: to avoid problems with determining the date of conception - girls need to keep a special calendar. Ladies mark all their menstrual days on the calendar.

So, do you already know the beginning of your last menstrual days? Then you need to add 40 weeks to it. Or count back just three months from it, and then add 10 days. This way you can calculate the baby’s birthday with a high probability.

Calculator for determining the day of conception

This calculator works on the principle of adding two weeks to the first day of the last menstrual period. Because it happens in the middle of the menstrual cycle. Such calculations are accurate if the menstrual cycle lasts 28 days.

And when the menstrual cycle lasts 30 days, there is a high probability that you will ovulate on the 15th-16th. There is an interesting fact: many girls believe that the date of conception is the day they had sex. It is not always so! Male sperm have the ability to reach the egg within 5 days! It depends on the quality of the male sperm and how mature the female egg is.

A very interesting fact: an egg can be attacked by up to 500 million sperm. The strongest one will win!

Why do you need to know the day of conception?

To know the date of birth of the baby, it is necessary to determine the date of conception of the child. You can even do this using an online calculator. Today there are a lot of them on the Internet. But whether you can trust them is up to you. For the best result, you need to have several calculation systems and compare them.

Inaccurate date

Absolutely impossible. A small number of women give birth at the time prescribed by the gynecologist. The birth of the baby may not occur at the 40th week, but even at the 38th. This is quite normal. If twins are carried, then mothers give birth prematurely. So, you need to consider as much as possible all the temporary options for the baby’s arrival into the world. And wait! You will definitely be a very good mother!

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

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

The ovulation process lasts 4 days and usually occurs 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 occur here.

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

To prepare for pregnancy, you can also use 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 the temperature. Before the temperature should rise by 0.2 - 0.4 degrees, there is a slight decrease. It is precisely the interval between these two phenomena that can be ovulation. To accurately determine the ovulation process, 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 be calculated even while at home, thanks to tests that are carried out on days 9-15 of the monthly cycle a couple of times a day. They indicate the presence or absence of a peptide hormone. If it is detected, ovulation should occur within 16-28 hours.

To conceive, you can use the above, but 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 baby born 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 loved one during the New Year holidays and Christmas. However, while waiting for the baby to be born, the expectant mother will need to endure hot summers and an icy season as winter approaches.
When conception occurs in the summer, the expectant mother can consume as many berries and fruits as she wants. But extreme heat will cause swelling 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 pay maximum attention to prevent colds and colds.
When conceiving a child in the fall, you don’t have to limit yourself to the number of walks in the fresh air that are beneficial for the expectant mother and baby. Autumn is the time to consume vitamins, but you should also be wary of various infections.

To summarize, we can say that it is realistic to choose the time of year for the birth of a baby and plan his conception correctly. But do not forget that in pursuit of the desired period of labor, you can be distracted from the most important thing - the health of the child, you just do not need to forget about it.

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

Favorable days for conceiving a child: menstrual cycle and ovulation

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

Each menstrual cycle is divided into three main phases:

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

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

Methods for determining ovulation

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

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

The best days to conceive according to the ovulation calendar

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

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

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

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

Best days to conceive according to ultrasound

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

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

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

Conceiving a child according to the lunar calendar

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

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

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

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

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

conclusions

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

Video “Favorable days for conceiving a child”

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

Reading time: 5 minutes

Doctors strongly recommend that women mark the beginning of each period on a calendar so that, based on this data, they can calculate the date of ovulation and calculate the period of conception of the child. Not every sexual intercourse leads to the fertilization of an egg. For a successful pregnancy to occur, a number of processes must occur in a woman’s body, which will be discussed below.

What is the period of conception

From the first day of the cycle, the body begins to prepare for pregnancy. Follicles mature inside the ovaries. One develops faster. At the moment the follicle ruptures, the mature egg penetrates the fallopian tube. This process is called ovulation. An unfertilized egg lives for a day. If fertilization does not occur, she dies and comes out with menstruation. Sperm are more viable. Some die on the way from the vagina, but those that penetrate the fallopian tubes wait for an egg for 3-4 days. The period of conception is a period in the middle of the cycle lasting 4 days: three before ovulation and one after.

What does knowing the date give?

To calculate timing of conceiving a child, you need to calculate the date of ovulation. Sexual intercourse should occur no earlier than 4 days before, and no later than 24 hours after it. This useful to know for those who dream of getting pregnant or, conversely, do not want children. If pregnancy has occurred, it is impossible to accurately calculate the day the child was conceived, but you can calculate when this happened most likely.

How to calculate the date of conception

To calculate favorable dates, you need to determine when ovulation occurs, in the following ways:

calendar method;
measurement of basal temperature;
ovulation tests;
folliculometry.

Any method has an error. Even a healthy female body is fickle. Sexual contact can cause premature release of the egg, and stress and fatigue can cause late ovulation. A woman can determine the onset of the ovulatory period by sensations. Indirect signs of ovulation:

pain in the lower abdomen;
mucous discharge from the vagina;
change of mood;
increased sexual desire.

Calculate the date of conception based on the last menstruation

Doctors consider the date of conception to be the first day of the last menstruation. The obstetric period exceeds the embryonic period by two weeks. With an irregular cycle, the difference between them is significant. The advantage of the method is that women know the date of their last menstruation. The calendar method for determining ovulation is suitable for regular cycles. For several months, record information about the beginning of menstruation in your calendar. Divide the average cycle length in half. If you add the resulting number to the first day of your last period, you get the date of ovulation.

Date of conception by date of birth

To calculate the day of conception of a child, you need to subtract a week from the preliminary date of birth and add three months. This is how the obstetric gestational age is determined. Add another two weeks to get your fertilization time. This is an imprecise method: not all babies are born at term. If you remember the estimated date of birth announced by the gynecologist, then by making calculations with it, you can guarantee greater accuracy. The advantage of this method is that it helps establish paternity without genetic testing.

Basal temperature measurement calendar

During ovulation, hormonal changes occur in the body, causing an increase in basal temperature. This is a natural process. Measure the temperature in the anus daily and record it in a table. To minimize the error, follow the rules:

take measurements at the same time in the morning;
without getting up, measure your temperature motionlessly for 5 minutes;
Perform measurements with one thermometer, since the error matters.

It is pointless to measure the temperature in other places; it only rises in the anus. If a woman is overheated or sick, the thermometer may show high numbers, but this will not be related to ovulation. The basal temperature calendar for an irregular cycle allows you not to miss the moment of egg release, but it requires painstaking work.

Calculate days of conception online

Women monitor their periods for delays. Previously, they were forced to cross out “red” dates manually; now there are services that record observations of the menstrual cycle online. The program will help you calculate the period favorable for conception and suggest safe days. The female calendar should not be used as a method of contraception. Record your basal temperature, mood, well-being, discharge, sex in apps. This information will help when planning a pregnancy and when visiting a gynecologist. Convenient applications:

Feminap (Android);
Menstruation: Women's Calendar (iOS);
4WomenOnly (Windows);
Flo – women's calendar of periods and pregnancy (Android, iOS).

Folliculometry

A reliable method of monitoring the stages of egg maturation is folliculometry. Painless ultrasound diagnostics are performed externally or vaginally. The gynecologist selects the timing of the examination: 7-12 days from the start of menstruation with a regular cycle and 3-5 days with an irregular one. Research is carried out daily or every other day before ovulation. If the egg is not released, an ultrasound is performed before the next menstruation.

Folliculometry is an accurate method that requires a visit to the clinic and financial costs, therefore it is recommended for women with:

infertility;
hormonal disorders;
preparation for artificial insemination;
stimulation of ovulation;
carrying out IVF.

Special tests

Pharmacies sell strips similar to pregnancy tests to determine ovulation. Diagnosis is based on the content of luteinizing hormone in the urine, indicating the readiness of the egg for fertilization. 17 days before menstruation, you need to conduct such a study 5 days in the morning and evening. In addition to tests that analyze urine, there is a perfect a reusable system that examines saliva.

Device works on the principle of a microscope. You need to drop saliva onto the glass and wait for it to dry. An ovulation microscope analyzes the remaining trace. Progesterone and estrogen affect the composition of saliva. The device has many advantages. To carry out a diagnosis, you do not need to look for a toilet. Thanks to accuracy and simplicity, you can calculate not only favorable days for conception, but also safe days.

These tests can be used to predict the sex of the baby. If sexual intercourse takes place on the day of ovulation, it will probably be a boy, since Y sperm are faster than X. If sex took place a few days before, then a girl will most likely be born. This result is explained by the fact that more viable X sperm have a better chance of waiting for the egg to be released.

How to find out the day of conception of a child when you are already pregnant

The doctor can determine the date of conception as accurately as possible by the level of the hCG hormone and ultrasound results. In the first trimester of pregnancy, the indicator for establishing the gestational age is the size of the uterus, which depends on the intrauterine size of the fetus. This is necessary to clarify the PDA (preliminary date of birth). At later stages, the expected day of conception can be assessed by the rate of development of the child and the baby’s movements.

Favorable time for conception

If you make love at a time favorable for conception, then your chance of getting pregnant is very high.

The ideal day is your ovulation. The probability of conception is 40%! One to two days before ovulation, the chances of getting pregnant are 30-35%. If sexual intercourse occurs 4-6 days before ovulation, this probability decreases to 10%. The days after ovulation, as well as after menstruation, cannot, of course, be considered absolutely infertile, but even the most liberal sexologist will not give you more than 2%.

There are several ways to determine the day the egg is released.

Arithmetic

For 6-12 months, you need to monitor your monthly cycle and write down its start and end dates, as well as its duration. Now you are ready to calculate.

Subtract 18 from the shortest and 11 from the longest cycle. For example, your shortest cycle is 25 days and your longest is 30: 25-18 = 7; 30-11 = 19. This means that conception is most likely from the seventh to the nineteenth day of the cycle. This method is very approximate.

Thermal

Every morning, without getting out of bed, measure your rectal temperature (in the rectum) and display the data on a graph. This must be done within 3-6 months. This is quite a sufficient period of time to establish a pattern of fluctuations. On the day of ovulation, the temperature reaches its lowest point and then rises again.

The most favorable days for fertilization are 4-6 days before ovulation and the next 1-2 days after the temperature rises. In total, the most likely days for conception, including the day of ovulation, range from 5 to 9.

Ovulation in most women occurs 12-13 days before the start of the next menstruation (with a regular cycle of 26-28 days long). This method is quite reliable, but long and unaesthetic.

Sensory Your vaginal discharge can also tell you when you are ovulating. At this time, they become more liquid and less viscous than usual.

It is best to draw conclusions about the onset of ovulation using all 3 of the above methods.

2. We need to move closer to a river or pond

Oddly enough, moving to this place can help. The fact is that the air near water bodies contains many so-called air ions - tiny air particles that accelerate cell division. Accordingly, more eggs will mature in a woman, and the number of sperm in a man will increase.

3. Put a heating pad on a woman’s stomach after intimacy

Heat dilates blood vessels, blood flow becomes more active, metabolic processes and reactions accelerate. As a result, female and male cells will begin to move faster towards each other.

Of course, you shouldn’t rely only on a heating pad, but you can try it as an additional remedy.

4. Men should drink a decoction of elecampane herb before contact.

This method is quite effective. Elecampane changes the composition of seminal fluid - it becomes more tenacious (the number of enzymes that seem to preserve sperm increases). This means that, once in the vagina, sperm remain active not for 3 days, but for a week. As a result, the likelihood of conception increases.

IMPORTANT!

Drinking four cups of coffee or other caffeinated drinks daily reduces your chance of conceiving by 26%!
