Without error, we determine the exact day of conception. Ovulation calendar for calculating favorable days for conceiving a child

The conception calculator is a simple program that will be useful to all women without exception: very young girls with a not yet established menstrual cycle, those who plan or, on the contrary, want to avoid pregnancy, as well as expectant mothers. Let us consider in more detail the situations in which the conception calculator is most welcome to calculate.

Monitoring the menstrual cycle. Gynecologists do not get tired of repeating that every woman should keep a calendar and accurately mark the dates of menstruation in it. Firstly, this is necessary in order to notice any deviations in reproductive health in time (reduction or vice versa lengthening of the cycle does not mean anything good). Secondly, in time to understand that pregnancy may have occurred. This is important for those who yearn to become parents and for their "opposites".

The conception calculator helps you calculate your ovulation by entering the correct average length of your cycle and the first day of your last period. In addition to ovulation, the program suggests which days are also potentially favorable for the onset of conception. That's when you need to especially "try". Those who do not want to have children yet, on the days marked in orange and green, it is better to do without sexual intercourse. Although, it is not at all a fact that this will help to avoid pregnancy. The calendar method of contraception has long been called low effective. So, it is better to use the online conception calculator for less responsible purposes, so to speak, and in conjunction with other means.

You can more reliably determine ovulation using 2 methods at once: for example, the calendar method and measuring basal temperature. And even easier and more reliable - ovulation tests. On the days that our conception calculator highlighted in green and orange, tests should be done. But first read the instructions carefully. It is similar to the usual pregnancy tests, but there is still some difference. As, for example, ovulation tests at the most likely time for conception, it is better to do 2 times a day - in the morning and in the evening, so as not to miss the right moment.

Another conception days calculator will serve well for expectant mothers who want to know the most accurate due date. Pregnancy lasts about 280 days. So, you can safely add 280 to the day highlighted in orange and get the approximate date of birth. Why approximate? The fact is that the duration of bearing a child depends on many factors. For example, a woman may give birth prematurely due to the nature of the cervix, or the amniotic fluid may break prematurely. Also, doctors may, for medical reasons, induce labor a little earlier. Situations are different.

Knowing the day of conception, you can set yourself the exact gestational age. It will be approximately 2 weeks less than the doctors will put. The fact is that gynecologists calculate the obstetric gestational age, and for this, an online conception calculator is not needed. It is only necessary to know the first day of the last menstruation, it becomes the first day of the obstetric gestation period. But sometimes you need to know the gestational age quite accurately, for example, when the doctor begins to suspect a delayed pregnancy, or if the uterus is too large or small in the early stages. In general, in order to identify a possible pathology, you need to know the approximate day of conception. But who is watching this? So it remains only to calculate the conception calculator.

Even for those who do not bother much with questions - how to get pregnant as soon as possible, but are already planning parenthood in the very near future, our calendar will also come in handy. The fact is that the baby's body, or rather all its organs, are formed in the very first days and weeks after the implantation of the egg in the uterine wall. And it is at this time, while there is no placenta, that the baby is most susceptible to any negative influences. Smoking, taking alcoholic beverages, certain medications, and so on can lead to miscarriage or serious pathologies in the development of the fetus. And the calculator of the days of conception will clearly show you approximately from what time you need to “take up your mind” (if you haven’t done this before) and remind you about the delay in menstruation.

Pregnancy is one of the most exciting and at the same time crucial periods in the life of every woman, and therefore it is not at all surprising that each of us wants to know the date of birth as soon as possible. However, this issue often causes numerous disagreements and disputes. Expectant mothers “torture” doctors with their questions, because they want to prepare for an important event, but they only shrug, because they are not able to accurately determine the date of the birth of the long-awaited baby.

The calculation of the expected date of delivery (ED) is carried out in several ways, each of which is indicative. That is, if, according to estimates, the baby should be born on January 1, then it is not a fact that this will happen with absolute accuracy on that day. Very often there are deviations from the expected date in one direction or another. And childbirth can begin either 2 weeks earlier or later. I bring to your attention a fairly simple, but very effective way to find out the probable due date of a child, which has been successfully used by many doctors in clinics for quite a long time.

Calculation on the last day of menstruation

4 Alternative Ways to Calculate Due Date

• 1. You can find out the due date, with a fairly high accuracy, by visiting the gynecologist's office. The doctor will not prescribe any tests for this, he will simply measure the size of the uterus, which will increase in size in accordance with the age of the fetus. However, this method of calculating the date of birth of the baby is effective only in the first trimester of pregnancy. In the later lines (in the 2nd and 3rd trimester), in each woman, an increase in the size of the uterus occurs with different intensity, depending on the individual characteristics of the organism.
• 2. You can calculate the date of birth by ovulation, which is the most favorable period in which conception is most likely to occur. On such days, a woman usually experiences an increased sexual desire. In addition, her secretions (cervical fluid) become more sticky and thick, basal body temperature rises by a few tenths of a degree, the cervix rises, and the mammary glands thicken and become painful.

• 3. Hardware calculation using ultrasonic waves can also be attributed to the most effective methods that allow you to determine the term of delivery with an accuracy of 1-3 days. The most correct calculations will be if ultrasound is done during the period of 11-14 weeks of pregnancy.
• 4. To declassify the secret of the date of birth of your child will help his first stirring, which usually occurs on the 20th week (in nulliparous) and on the 18th - in the second and subsequent pregnancies. In ancient times, when there was no ultrasound, this method of calculating the due date was almost the only one.

Deviation from the deadline - is it the norm?

How do the features of the menstrual cycle affect the date of birth?

If your pregnancy is confirmed, then I wholeheartedly congratulate you on this bright event. Carrying a baby is a wonderful, unforgettable and special period in a woman's life. And this boundless happiness is not given to everyone - always remember this!

Nothing compares to carrying and giving birth to a baby. And no life problems, difficulties and troubles can exceed the significance of this event. Therefore, I can’t even imagine why a woman needs to know exactly the day on which the conception occurred. However, many of us are trying to determine the date of conception of a child, and it must be admitted that this is quite difficult to do.

How to determine the day of conception?

Calculating the exact date of conception, if it has already taken place, is simply unrealistic. It is only possible to determine the probable day of the conception of a child, but this date will never be 100% correct. This is because, in fact, conception can only take place during the period of ovulation. And if you do not calculate ovulation every month for a long period, then you can only approximately calculate the days on which it could take place in the last cycle. To do this, subtract 14 days from the date on which, according to your assumptions, the next menstruation should begin. It is believed that ovulation occurs on average 14 days before the start of the next menstruation: with a 28-day cycle, it occurs on the 14th day of the cycle, with a 30-day cycle, on the 16th day, with a 24-day cycle, on the 10th day, and so on. Further. But this is a very arbitrary guideline.

More or less accurately, the date of conception can be determined by a specialist conducting an ultrasound examination. He will give you an approximate gestational age, which also cannot be considered unmistakably correct.

The fact is that ovulation can be influenced by a large number of different factors that are not able to take into account any of the known methods for calculating the date of conception and childbirth.

How to determine the day for conceiving a child?

If you are trying to determine the most likely or, then everything is much simpler here. To do this, you need to calculate with maximum accuracy the day on which you ovulate. There are many different ways to do this:

• by basal temperature: ovulation occurs after a temperature drop, observed a day before the release of the egg from the follicle (there is a decrease in BBT by 0.1-0.2 degrees). Then, after the onset of ovulation, the indicators increase by 0.2-0.5 degrees and exceed 37 ° C;
• according to the nature of the vaginal mucus: before ovulation, sticky and thick in the first phase of the cycle, vaginal discharge becomes viscous and transparent, like egg white. The release of a mature egg may be accompanied by damage to the blood vessels, which a woman observes with slight impurities of blood in the vaginal discharge in the middle of the cycle;
• for ovulatory syndrome: some women with hypersensitivity may feel pulling pains from the active ovary and even complain of a short-term malaise during this period;
• by using: works on the same principle as a pregnancy test, only unlike the latter, it reacts to an increase in the concentration of the so-called fertility hormone (LH - luteinizing hormone);
• folliculometry method: the process of maturation of the egg is monitored by ultrasound, which allows you to accurately determine the day of ovulation.

In addition, an experienced gynecologist can determine quite accurately the approach of ovulation while examining a woman on an armchair.

The most reliable result can be obtained by combining several methods at once.

Few days to conceive

Finally, we note that even knowing the exact date of the sexual intercourse that caused the pregnancy, it is impossible to say with certainty that it is also the date of conception of the baby. After all, the path of sperm to the egg can take more than one day. Moreover, a sperm cell that has already arrived at its destination can wait for the egg to leave the follicle, if this has not happened yet. Therefore, experts say that theoretically, the conception of a child can take place as a result of sexual intercourse, carried out a few days before ovulation and a day or two after it.

Thus, you cannot accurately determine the day of conception of a child, but looking forward to his birth and becoming the best mother in the world for him is within your power! Is there anything more important?

Happiness to you!

Pregnancy is the most important stage in the life of any mother. The health of the future baby depends on the preparation for it and its course. To determine the exact duration of pregnancy and childbirth, the date of fertilization is important. There are several ways to determine the date of conception, it remains only to choose the most optimal one.

It is well known that a woman can become pregnant only during the ovulatory period. Directly at these hours, the female cell, ready for conception, leaves the ovary in the direction of the uterus. The life expectancy of an egg is small and rarely exceeds 36 hours, so the chances of conceiving a child during one cycle for spouses are negligible. When spermatozoa penetrate the vagina, under the most favorable conditions, a tiny part of them can live there for about a week. That is why the process of conception can take place a few days before and on the day of ovulation. How to determine the day of fertilization?

With one sexual intercourse, about 500 million spermatozoa enter the vagina, which modestly accumulate at the posterior vaginal wall next to the cervix. For conception to occur, the sperm must reach the mature egg in order to properly fertilize it. For this, the spermatozoon has a rather difficult path:

• First, it passes 2 cm of the cervical canal;
• Then overcomes 5 cm of the uterine cavity;
• Then his task involves overcoming 12 cm of the fallopian tube.

Only after passing the cherished 19 cm, the sperm enters the meeting point - the ampullary section, where the “date” with the egg takes place. It takes about three hours for sperm to overcome this path, and the female body strongly opposes this process. In fact, the vagina is an aggressive environment for spermatozoa, in which most of them die. During the period of being in the vaginal environment, the spermatozoon dies after 2 hours. Therefore, a sufficient number of viable and active sperm is important for fertilization.

Process Features

Many of the spermatozoa cannot reach the egg, becoming entangled in the epithelial layer of the fallopian tubes. But they can wait here for the release of the egg, since they are able to live here for about 5 more days. At the same time, favorable conditions for fertilization at 37 ° C are created at the meeting point of the sperm and the egg. But getting to the egg is not enough, you still need to break through its defenses. This is also taken into account by nature, therefore, in the head of each sperm there is a specific enzyme that dissolves the membrane membrane of the egg. When one spermatozoon manages to fertilize a female cell, the composition of its shell changes so that not a single sperm can get inside, which die within 48 hours.

The egg enters the uterus approximately four days after fertilization has occurred. Attachment takes another three days, after which the conception can be considered accomplished. It was at this time that chorionic gonadotropin begins to actively enter the blood, which is determined by rapid pregnancy tests.

When conception happened

To determine the day of conception, it is necessary to accurately calculate the ovulatory period, then compare it with the date on which unprotected intercourse occurred. Conception usually occurs in the middle of the female cycle. Therefore, with a monthly cycle of 28 days, you need to count 14 days from their beginning. In a similar period, the ovulatory process and conception occur. When making a calculation, it is necessary to take into account that sperm can fertilize a female cell only for a day and a half, but the viability of sperm can last up to 5 days (for some, up to a week). Therefore, even knowing the number of sexual contact that has occurred, you should not expect that it will coincide in date with conception.

There are two types of gestation periods - true or obstetric. The true or specific period is counted from the ovulatory period and the moment of fertilization. He usually lags behind obstetric by about half a month. The obstetric period can be calculated by relying on and comparing certain factors such as the beginning of the maturation of the female germ cell, the formation of the fetal egg and the formation of the fetus. This calculation starts from the start date of the last menstrual bleeding.

Proven Ways to Calculate a Date

There are other proven methods for determining conception. After confirming the fact of pregnancy, the obstetrician asks every woman at a gynecological appointment in detail when the last menstruation began, the duration of the cycle and other information of this kind. Some doctors, in order to determine the exact date of conception, are guided by the period of the menstrual delay, although the main reference point is still the day the menstruation begins. Therefore, women are advised to keep a women's calendar, in which you need to enter all the information regarding the beginning and end of menstruation. There are several proven options for finding out the date of conception.

1. With the help of a gynecologist. This period and date of fertilization will be very relative, in order to more accurately determine the date of conception of a child, additional examinations and medical calculations must be carried out.
2. Calculate the due date for the last menstruation. This is a fairly common technique, but it is applicable only when the cycle is constantly the same, does not float and does not go astray, menstruation constantly comes on a certain day. In cases where the cycle is constantly shifting to a decrease or increase in days, it will be quite difficult to calculate when exactly delivery will occur.
3. When registering, each woman is sent for ultrasound diagnostics, where the date of conception is determined, as well as the gestation period. The ultrasound method is the most reliable, only such a study can show the presence of pregnancy only at a 5-7-week period, not earlier. But you can find out when the baby should be born using ultrasound diagnostics in the period of 9-16 weeks. If the fetus develops with deviations (too large or small), then ultrasound can give erroneous calculations.

These methods are used by gynecologists to identify the exact day of conception and establish the timing of fetal development. In the process of calculations, it is necessary to take into account the individual characteristics of the mother's body, the presence of probable deviations in fetal development, etc. Also, one should not discount the fact that the newborn will be active for the birth a little earlier than the calculated period, or, conversely, will linger in the mother's womb for more for a week.

Calculator

So, in order to determine when conception took place, it is necessary to have information about two dates: the first day of the last menstruation and the days when there were sexual intercourse without contraception. It is recommended to write down these dates, because, as practice shows, they are forgotten quickly enough, and already at a gynecological appointment, it is difficult for a woman to remember when the last bleeding was. How to find out the desired date, knowing the above numbers?

Normally, the duration of gestation is 280 days from the day of conception. That's 10 months or 40 weeks. So, you know the date of the beginning of the last menstruation. You need to add exactly 40 weeks to this number. The resulting result will be the number when the baby is supposed to appear.

If you need to determine the date of conception of a child, then everything is also simple here. Ovulation occurs in the middle of the menstrual cycle. With its duration of 30 days, then fertilization will occur on the 15-16th day. The statement that the egg is fertilized on the day of sexual contact is erroneous. Sometimes several days pass between sex and conception, which depends on the degree of maturation of the egg, the viability and mobility of the spermatozoa.

What gives knowledge of the date

Knowing when conception occurred is important in order to calculate the time of delivery. In addition, such information will help to monitor fetal development. Specific changes occur weekly with the fetus, in order to find out whether this is the norm or a deviation, it is necessary to reliably determine the gestation period. This will help control the processes of growth and development of the fetus, determine whether the pregnancy is proceeding favorably, etc.

In addition, knowing the exact day of conception, you can find out the exact date of birth, determine the time when mom goes on maternity leave, etc.

Conception period

It has already been noted that even with the exact date of sexual intercourse that led to the onset of pregnancy, it is impossible to consider this day as the date of conception with absolute certainty. Since spermatozoa can reach the female cell for several days, conception can also be determined by several days, covering the ovulatory period. When patients are interested in how to determine the dates of conception, doctors usually say that conception can take place after a sexual relationship that occurred a few days before the ovulatory period and a couple of days after it ends.

In obstetric practice, it is quite rare for childbirth to occur at the scheduled time, because a newborn can be born not at 40, but at 42 or 38 weeks, which is not a deviation. Therefore, the preliminary date of delivery should be treated as an approximate guideline.

Pregnancy is a joyful, albeit very difficult period in the life of every woman. It is very important to correctly calculate the date of conception, because this will help in the future to determine as accurately as possible the entire period of pregnancy.

An accurate calculation of the moment of fertilization allows you to determine the date of birth, so every girl should treat the counting process with extreme care and responsibility. Correct calculations allow you to prepare well for the birth of your baby. As a rule, the calculated number differs from the real one by a maximum of a day or two.

Calculate the date of conception by birth. The fastest and most accurate counting method

This method is only suitable if the baby has already been born. You may want to know the exact number. Recent medical studies claim that 94 percent of women give birth on the 266th day after fertilization. To calculate the date of conception by birth, subtract 266 days from the number of the child's birth. The resulting number is the day of the last ovulation.

Calculate conception date: calculator

Currently, there are many online services for calculating and determining this day. Unfortunately, not all of them are able to accurately cope with the task. It is very important to know all the parameters and choose a quality service for the calculation.

The calculator should take into account the day of your last period. Pay attention to the average length of the menstrual cycle. It should also be included in the calculator. Independently determine the average value of the duration of the second phase of the cycle. Enter all data into the calculator. After a few seconds, it will show you the day of your last ovulation - this is the day of fertilization.

Ultrasound calculation method

The method of ultrasound diagnosis of the uterus can also calculate the date of fertilization. Not always the expectant mother can determine when her baby was conceived. Pregnancy is often unplanned, it is in such cases that one of the calculation methods should be used.

A gynecologist can help calculate the date of conception. Usually, it is possible to determine the onset of pregnancy by ultrasound scanning after the tenth week. Keep in mind that your doctor may not accurately determine this day if you do not remember when your last period was, or if your cycle is irregular.

Determine the date of conception by the last menstruation

The expectant mother can determine the day when life was born inside her. It is always counted from the day of your last period, although in fact, pregnancy occurs already after two weeks after fertilization. The female cycle is always included in the calculation.

The error in the calculation occurs if your cycle is irregular. In this case, you can accurately calculate the date of conception using hCG.

hCG

HCG (or gonadotropin) is a human protein hormone. In pregnant women, the level of hCG rises sharply, which indicates a successful pregnancy and a healthy fetus. It is to increase this hormone that pregnancy tests are tuned, which are able to accurately give the result three to four days after the delay in menstruation.

The hormone is produced throughout the entire period of pregnancy, so it is very easy to calculate the date of conception, starting from medical tests, namely the presence of the hormone level in the body.

Together with your doctor, determine the period when the level of the hormone in your body has increased - in fact, this day coincides with ovulation, it is the day of pregnancy.

In reference books, you can find information about what level of the hormone should be in a woman's body in each week of pregnancy. According to such information, immediately after conception, the level of hCG in the body rises from a value of 3 to 10.

Best day definitions

As mentioned above, the best time to conceive is the exact day you ovulate. In addition, three to five days before ovulation, refrain from sexual intercourse. Never drink alcohol, smoke or eat fatty or other unhealthy foods. All this negatively affects the reproductive system of women, especially during the period of ovulation.

Maintaining a healthy lifestyle should concern both partners, because malnutrition and alcohol consumption destroy both female and male reproductive cells.

Try not to breathe chemicals: varnishes, paints, enamels, etc. Avoid them throughout your pregnancy. Before buying household chemicals in a house where there is a pregnant woman or a small child, carefully read the composition of the product. It should not contain phosphates and heavy chemical components that can corrode the skin and enter the respiratory tract.

If recently one of the partners began to get sick often even with the most minor diseases (cough, SARS and others), it is still worthwhile to postpone this issue until complete recovery and improvement of well-being.

1. At least six months before conception, improve your general level of health (refusal of fatty foods, alcohol and tobacco products).
2. Be examined by a doctor for the presence of pathologies of germ cells and find out in general your level of health of the reproductive system.
3. Make sure both partners are free of syphilis, HIV, and other sexually transmitted diseases.
4. If you find any health problems, be sure to consult a gynecologist for timely assistance.

All of the above tips apply to both men and women. Subject to all the rules, pregnancy will be easy, and the baby will be born healthy.

It is not easy to calculate the date of conception of a child, since each woman is individual. But sometimes she can tell the doctor exactly when fertilization occurred. And here it is worth trusting the maternal instinct, since in 99 percent of cases the expectant mother is right, and the baby is born exactly when she says, and not the obstetrician-gynecologist's calendar. The same can be said about the ultrasound, which is sometimes wrong for several days.
