Every woman, especially when the moment of pregnancy is right, should be attentive to her health. One part of this process is tracking your menstrual cycle and ovulation. To make the process more efficient, we offer an online calculator that will allow you to determine the favorable days for conceiving a child.
We suggest using the service "Calendar of conception and contraception" - by indicating the initial data: the first day of the cycle and its duration, you can determine favorable days for the conception of a boy or girl, the beginning of the next cycle, ovulation. The conception calendar cannot guarantee a 100 percent result, since a lot depends on the body and everything is individual. The work of the calendar is based on average statistical data.
Your calendar
Fill out the form above. Specify the First day of the cycle, the duration of the cycle and click "Calculate"
Explanations
1 - the first day of the cycle;
2 - the beginning of the next cycle;
3 - safe sex;
4 - conditionally safe days;
5 - conceiving a girl;
6 - the conception of a boy;
7 - ovulation;
8 - feeling unwell (PMS).
What is a calendar?
The conception calendar is an online form in which you just need to enter the first menstruation and the duration of the cycle. The program itself will calculate when ovulation will occur, and which days will be the most successful for fertilization (and dangerous for someone!).
To make the operation of the program that calculates the date of ovulation and the onset of pregnancy clear, we will give the main factors that were taken into account when creating it:
- Many women (although it all depends on the individual factor) ovulation occurs towards the middle of the cycle. The calculator calculates the middle of the time interval after the beginning of menstruation and their end, and also calculates, taking into account the most dangerous or, conversely, favorable days on which pregnancy can occur
- Fertilization. Does not occur during menstruation and at the end of the cycle: on these days, conception almost does not occur
The calendar also calculates relatively safe days when pregnancy is unlikely. These are the days at the beginning and at the end of the cycle. In the middle of the cycle, the calculator marks the day of ovulation, and can also determine the day of the beginning of the next period.
To calculate the days of ovulation, you just need to enter your period data into the online calculator. After that, press the button, and the calculator itself will calculate the day of ovulation and a favorable day for conception. Of course, there is no guarantee that the indicated data will be absolutely accurate, but they will be able to roughly indicate to you the dangerous days on which ovulation and the onset of pregnancy occur.
The calculation of the day of ovulation and potential pregnancy can be done for a whole year. This way, you will know in advance when to plan intercourse, depending on whether you want to get pregnant or not.
The form of the calendar is very easy to use. The required days are marked in different colors, so that they immediately catch the eye. The pregnancy calendar will help you speed up the conception of a child and get closer to the long-awaited event.
How to determine the gender of a baby?
Any parent who wants to have a child thinks about how to calculate its gender. Traditional and traditional medicine offer different ways to do this.
A calculator for determining the sex of a child is another technique, however, it does not give 100% of the result. The conception calendar of a girl or boy can be compiled for yourself if you use the same pregnancy calendar. The conception calendar for a girl or a boy is based on the theory that a girl is obtained if sperm cells entered the woman's body before ovulation and stayed there for several days. If the sperm cells entered the body of the expectant mother immediately after ovulation, then it turns out a boy.
The conception calendar for a boy or girl, of course, also does not give a 100% guarantee, but it allows you to get closer to the desired result. Doctors have proven that fertilization after ovulation leads to the birth of a boy, and before ovulation - a girl.
After you have learned the favorable days for conceiving a child and determined what gender the baby can be, it is time to plan a pregnancy.
To calculate dangerous or, conversely, favorable days for conception after menstruation or to determine the sex of the child, a woman will have to record some data about herself and her health. This data will help her create her own calendar of conception of a boy or girl. However, it is worth remembering that the day of ovulation and favorable days for conceiving a child of one sex or another, calculated by an online calculator, are relative. The body of every woman is individual and unique, and many more factors affect the determination of the sex of the child.
Is it possible to plan the sex of the baby by ovulation? The birth of a long-awaited heir is always a great joy for expectant mothers and fathers. If during the first pregnancy, parents are often equally happy with both the girl and the boy, then in the future they most often dream of a child of a certain gender. How to make adjustments to the plans of nature, and it is planned to conceive the desired son or beautiful daughter? It turns out that it is quite possible to calculate the sex of the child by ovulation. Read about how to identify a girl or boy, and what to do for those who dream of solemnly leaving the hospital with a blue or pink envelope in their arms, read this article.
Ovulation - what is it?
Ovulation refers to the physiological process of maturation of the egg in the middle of the menstrual cycle. A fully matured and ready-to-conceive egg cell emerges from the follicle, from where it moves through the abdominal cavity into the fallopian tube. The fallopian tubes are lined with special villi from the inside, for which she clings and waits for the sperm. If conception occurs, then the fertilized egg descends into the uterine cavity, where the fetus begins to develop. An unfertilized egg is released during menstruation, then the whole process resumes.
The egg cell viability is 24 hours. The sperm can remain active for up to 2-3 days. Most likely, conception will occur on the day of ovulation or 2-3 days earlier. This phenomenon is based on this method of planning the sex of the unborn child.
As you know, the sex of the unborn child depends on the chromosomes of the sperm that fertilized the egg. There are two sets of chromosomes - XX and XY. The first is responsible for the birth of girls, but in the second case, a boy will be born. Chromosomes of each type have their own characteristics, which allow planning a child of the desired gender. Spermatozoa with a female chromosome set are distinguished by high vitality, their activity is much lower. In turn, the Y chromosomes are more active, but they do not live long. When intercourse takes place 4-5 days before ovulation, the male chromosomes lose their vitality, which increases the likelihood of having a girl. If conception occurs right at the time of ovulation or 1-2 days before it, the eggs will reach more active "boyish" sperm, and the percentage of conceiving a son is much higher.
How to calculate the moment of ovulation?
Considering that the method that helps to know how to calculate the sex of a child during ovulation directly depends on the accuracy of the cycle. It is necessary to calculate the days when conception is most likely. Even the slightest irregularities in the menstrual cycle can significantly affect the result of conception. For women who have their period regularly, it will be easy to find out the day of ovulation. This can be done using popular methods:
The easiest and fastest way to determine if ovulation has occurred is a rapid test, which is sold in many pharmacies. In its action, it is much like a regular pregnancy test and allows you to get a quick and accurate result.
Less accurate, but quite effective, is the conception calendar, which will help in determining ovulation. For example, on a 28-day cycle, ovulation will occur 2 weeks after your period starts. By simple counting, a woman can mark the days most favorable for conception and mark them on the ovulation calendar.
You can calculate ovulation by measuring your basal temperature regularly. The method is rather troublesome, but it is highly efficient. In the morning, immediately after waking up, a woman needs to measure her rectal temperature, the data obtained should be entered into a graph. On days when the temperature reaches its peak, the likelihood of conception is highest. Scheduling the sex of a baby by ovulation has become very popular today.
When determining the days of ovulation, it is also worth considering the fact that the menstrual cycle can be subject to disruptions and errors, even in healthy women. The most common reasons for its violations are:
- various diseases;
- taking medications;
- a state of prolonged stress.
In order to achieve a successful predictable result, using sex determination at the onset of ovulation, it is recommended to calculate the day of egg maturation every month. This will minimize potential errors and see the desired two stripes as soon as possible.
How to conceive a boy?
Determining the sex of a child by ovulation is of interest to many married couples. In order for the long-awaited heir to appear in nine months, it is necessary to ensure that the conditions are calculated under which the fertilization of an egg by a sperm with XY genes would be most likely. Given the high activity of this type of germ cells, it is necessary that sexual intercourse occurs on the day of ovulation, when the readiness of the egg for fertilization is highest. Faster "boy" sperm cells, in all likelihood, will achieve the desired goal sooner than the tenacious, but slow "girl" cells.
To conceive a boy this month with the maximum probability, you should repeat intercourse again in the morning of the next day.
How to get a girl?
With a high mobility of XY chromosomes, they fail much faster than spermatozoa with a set of XX. It is worth calculating sexual intercourse 4-5 days before the day when ovulation should occur. During this time, "boy" chromosomes will lose activity, and those responsible for the birth of a girl will be able to achieve their goal.
How to improve the success of conception
Regardless of whether you want a boy or a girl, several methods will help to increase the efficiency of conception:
- Do not rush to the shower immediately after intimacy. After intercourse, you need to lie down for 2-3 minutes. The likelihood of fertilization will increase.
- Try to limit the stress in your life. Constant anxiety will not have the best effect on the body, which decides to postpone conception until better times.
- It is advisable to pay attention to your diet and maintain a healthy weight. On the eve of the planned conception, it is better to get rid of those extra pounds. Or vice versa, gain the missing mass. Weight deviations can affect the regularity of your monthly cycle.
Determining the sex of the child using folk methods
In addition to scheduling sex for ovulation, there are many alternative methods that can significantly increase the likelihood of having a daughter or son. Naturally, their probability will not be so high, but why not try all possible options when it comes to such an important matter as conceiving a child?
One of the most effective ways to determine the sex of the unborn baby is a special diet, which can increase the likelihood of pregnancy with a child of the desired gender. To give birth to a little hero, during pregnancy planning, it is worth leaning on red meats, for example, Polish shank, nuts, fruits (peaches, apricots and bananas), salty and spicy foods. Due to the high content of elements such as sodium and potassium in these products, they will help to form an alkaline environment in the area of the internal genital organs of a woman, which significantly increases the activity of the XY chromosomes.
If you sleep and see a charming daughter in princess outfits, you should often eat fish, vegetables and fruits (preferably green), dairy and sour milk products, as well as pumpkin and sunflower seeds. They are rich in magnesium and calcium, which maintain a high acidity in the internal environment.
For those who care what gender their child will be, it is also worth listening to folk signs. For example, our ancestors believed that in the heat there is a high probability of conceiving a son, but the daughter, most likely, will work out in cold weather. The frequency of sexual intercourse can also affect the sex of the child. It is believed that prolonged abstinence will help conceive a son, but those who dream of a daughter should have sex regularly.
Signs indicating the sex of the child during pregnancy
In those days, when there was no ultrasound, our ancestors could find out with almost 100% probability who would be born to a future mother. It was possible to find out the gender by special features, which even today work almost flawlessly. For example, a neat, slightly pointed belly indicates that the son is sitting inside, and if the belly is round and the protruding sides are clearly visible, then, most likely, through 
a daughter will be born in the family for several months.
About who will be born to the expectant mother, her gastronomic addictions can tell. It is believed that if a woman relies on spicy and salty foods during pregnancy, this is the birth of a son. Well, if a pregnant woman relies on dairy products, flour and sweets, she will have a female child.
Does ovulation scheduling work?
Those who want to get a baby of a certain gender using sex planning based on ovulation have a quite reasonable question: what is the real effectiveness of this method? As many couples say, in most cases, counting auspicious days for conception really helps to fulfill the dream of a son or daughter, so it deserves your attention. Moreover, the scheduling method is scientifically substantiated, which means there is no reason not to trust specialists.
The action of scheduling sex on the days of the monthly cycle can be explained by natural processes that regularly occur in the human body. Knowledge of the laws of conception will help to correct the sex of the child in an absolutely harmless and natural way.
The only drawback of this method is a sufficient percentage of errors, although in practice they do not happen very often. For parents who are expecting a long-awaited pregnancy, the most important thing is that the children are healthy and happy.
As soon as a woman finds out about a long-awaited pregnancy, she immediately has many questions, one of which is -how to find out the gender of the unborn child? Today, many new ways to study expectant mothers have appeared, but the question of how to determine the sex of the child in the first weeks (or even in the first days) of pregnancy remains open.
Which of them are considered the most effective and what are they based on?
How is a child of a certain gender formed?
To answer this question, you will have to recall the school course in biology. The woman's egg cell carries the X chromosome, and the male sperm - the X or Y. If the egg is fertilized with the Y chromosome, then after the allotted time, the couple will have a boy, and if X, a girl can be expected.
It is difficult to predict this natural process in advance, to calculate the sex of the child or to influence it in any way, therefore, in the first weeks after conception, determining the sex of the child remains a mystery for both future parents and doctors.
What affects the gender of the baby?
There are many theories about the influence of various factors on the formation of a child's sex, but so far none of them has been 100% confirmed. For example, there is a statement that the future sex of the child depends on the mother's weight and her nutrition.
According to some studies, women who weigh less than 54 kilograms are more likely to give birth to girls, and more fat women mostly have boys. Indeed, for the development of the male body, a little more nutrients are required than for the female, but the weight of the expectant mother still cannot be a guarantee of the birth of a child of a certain gender - there are a lot of cases when small, fragile girls successfully give birth to boys.
The same applies to theories regarding the age of future parents: hormonal changes that occur over the years in the human body can affect the sex of the embryo, but are not a determining factor.
Other studies say thatcalculate the sex of the childit is possible with the help of a certain diet. So, in order to give birth to a girl, expectant mothers need magnesium and calcium, that is, eggs, onions, dairy products, nuts, etc. But you can "order" a boy with the help of such products as fish, meat, legumes and fruits - that is, those that contain sodium and potassium.
In addition, acidic foods and drinks (in particular, natural fruit juices without sugar) are considered quite effective in planning the sex of the unborn baby: nutritionists advise women who want to conceive a girl to regularly consume them immediately before conception. This fact has a completely scientific justification - thanks to acidic products, the environment in the vagina also becomes acidic, due to which sperm with the Y chromosome quickly die.
But in any case, the fundamental role inplanning the sex of the unborn childonly Mother Nature plays, and future parents are unable to influence her decision. The only thing they can do is try to determine the sex of the baby before birth, using existing methods and techniques.
Methods for determining the sex of the baby
The most affordable way to determine the sex of a child today is considered to be an ultrasound scan, but the problem is that this can be done only at a specific date (after about 16-17 weeks of pregnancy). But what to do if, for some reason, you need to know it earlier? It is practically impossible to do this in advance with a probability of 100% today, so scientists are not abandoning their attempts to find a method that will allow not only to calculate the sex of a child immediately after conception, but also to plan it in advance.
The most popular and effective are severaltests to determine the sex of the child, which are based on various factors: parental blood, date of conception and special tables (Japanese and Chinese). You can test each of them in practice and make sure of their reliability below.
Determining the sex of the child by blood renewal
Methods for determining the sex of a child by the blood of parents have been known to scientists for a long time, and one of them is based on the date of blood renewal. There is an opinion that the complete renewal of blood, mucous membranes and tissues regularly occurs in the body of every person, and in men the frequency of this process is four years, and in women of the opposite sex - three. That is, if at the time of conception the woman's blood is "younger" than the man's, the couple will have a girl, and if on the contrary, then a boy.
It is rather difficult to say anything about the reliability of this method, since according to some data it "works" in 80% of cases, and according to others - in 50%. But experts say that if the calculations are done correctly, the couple has every chance of getting an answer to their question with a fairly high probability.
To calculatebaby gender by blood renewalyou need to know the date of conception of the baby, as well as the dates of birth of the future father and mother. True, it is important to remember that there are many factors that can speed up the process of blood renewal: these include transfusions, operations, major blood loss or donation. In this case, the countdown should not start from the date of birth, but from the day when the last major blood loss occurred.
Determining the sex of the child by the blood group of the parents
The method is based on the theory that the blood groups of the future father and mother have a great influence on the formation of the baby's sex. In other words, women and men with certain blood groups are more likely to have a baby of a certain gender. Of course, this method has the right to exist, but its reliability is subject to great criticism.
The problem is that the table for determining the sex of a child by blood implies one result for one pair of parents, but after all, each of us knows cases when children of different sexes grow up in the same family.
Determining the sex of the child by the Rh factor of the parents
To determine the sex of the baby in this way, it is enough to compare the Rh factors of his parents. To do this is as easy as shelling pears: if the rhesus match, then the couple will have a girl, and if the indicators are different, a boy.
True, as in the case of calculating sex by blood group, one can strongly doubt the reliability of the result obtained, because he claims that either one boy or one girl can be born to a particular couple.
Determining the sex of the child according to the Chinese table
This method does not have any scientific substantiation, and it is based on the observations and practical experience of several generations of Chinese at once. He says that a woman at a certain age can conceive or give birth to a boy or girl only in certain months of the year.
According to researchers, the first mention of the method dates back to the XII century, anddetermining the sex of the child according to the tablehelped many monarchs from the Middle Kingdom to plan the gender of their heirs. Howfind out the gender of the child according to the table?
It's very simple - you need to know the month of birth of the expectant mother, as well as the month of conception or the expected birth of the baby. By the way, modern parents also talk about its high efficiency of the Chinese table - according to estimates of couples who used this method, the probability of getting the correct result is about 90%.
To determine the gender of the expected baby according to the Chinese table, simply find the corresponding cell in the table - the intersection of the line of your age and the column - the month of conception.
Interestingly, using this table, you can also plan the sex of the child. In the row for your age, select the months in which a boy or girl is most likely to arrive. Subtract 9 months from the selected month, and you will get the estimated month of conception.

Determining the sex of the child according to the Japanese table
Determining the sex of a child according to the Japanese calendar, which came to us from the Land of the Rising Sun, is very similar to the determination according to the Chinese table, and is also based solely on practical observations. The difference between them is that the first takes into account not only information about the mother and the month of conception (or the expected month of the child's birth), but also the date of birth of the father. Thus, the Chinese methodology can be called more flexible and, accordingly, more reliable.
The only problem some couples may face is the difficulty in determining the month of conception. For example, if a woman ovulates on the 31st, conception is likely to occur on the 1st and 2nd of the next month, because the life span of sperm is from 3 to 5 days. The accuracy of the method according to various data is from 70 to 90%.
To determine the sex of the unborn child according to the Japanese table, you need to find the number corresponding to your pair in table 1. Then we find this number in the top row of Table 2. In the column of the corresponding date we find the month in which conception took place. Moving along this line to the middle of the table, we determine the probability of having a boy or girl by the number of crosses - the more there are, the greater the probability.

Determining the sex of the child by the date of ovulation or the date of conception
Every woman knows that conception can occur only on certain days of the month: on average, it is two days before ovulation, ovulation itself and two days after it. A technique that allowscalculate the sex of the child by the date of conception(more precisely, the date of ovulation), is based on "behavior" and the characteristics of the X and Y chromosomes.
According to studies, "girl's" sperm (that is, carriers of the X chromosome) are slow enough, but more tenacious, so they can stay in the uterus from 2 to 4 days and calmly "wait" for ovulation. But spermatozoa with the Y sign, on the contrary, are very mobile, but their lifespan is very short.
That is, if intercourse occurred 2-4 days before ovulation, then there is a high probability that the couple will have a girl, and if exactly on the day of ovulation (or immediately after it), a boy can be expected to appear.
Method for determining the sex of the child Freiman-Dobrotin
Quite a complicated calculation. But it is considered one of the most accurate. It's good that we have a calculator)
Tables: O - father and M - mother
First, in table O1, we find the intersection of the year of birth of the father and the year of conception of the child, remember or write the number into the intersection.
And so on all tables from the first to the fifth number.
Then we put together the obtained numbers and, according to table O6, we find the final coefficient.
Similarly, we do all the actions for the mother according to tables M1-M6
In the end, we look at who has a higher final coefficient, if mom has a girl, if dad has a boy. If both are zero, there will be a girl

Determination of the sex of the child by the Budyanskikh method
Calculation method:
1. If you use the mother's date of birth in the calculations, then you need to determine her approximate date of conception. To do this, subtract 9 months (approximately 226 days) from the mother's date of birth.
Next, you need to determine the even or odd year of the mother's conception.
Further, according to the table, find the type of the mother's cycle: in the first column, look for the appropriate month of the mother's conception, and look for the intersection with the type of year (even or odd) - the intersection will be the type of the mother's cycle.
2. By the preliminary date of the conception of the child, do the same steps as the mother. Determine the parity of the year of conception of the child, look in the first column for a suitable interval of dates in which conception is planned and for the intersection of the type of year of conception and the date of conception - the type of the child's cycle will be indicated.
If the type of cycle of the mother and the type of cycle of the child are the same, then there will be a girl, if they differ, then there will be a boy.

Is it possible to predict the sex of a child with 100% probability?
Unfortunately, none of the methods listed above can give 100% accurate results. Even specialists in ultrasound diagnostics sometimes make mistakes: for example, the fetus can turn so that it will be very problematic to determine the sex of the child.
In addition, until the 18th week of pregnancy, the male and female genitals are very similar, so even an experienced doctor can confuse them.
There are only two ways to find out the sex of a child for sure:
- ECO. When performing in vitro fertilization (IVF), doctors usually determine the sex of the embryo before transplanting it into the uterus. But doing such a study only at the request of parents in most countries is considered unethical, therefore it is carried out only in order to exclude genetic pathologies characteristic of men and women.
- Intrauterine tests... These most commonly involve amniocentesis and chorionic villus sampling and are performed between 15-18 weeks and 11-14 weeks of gestation, respectively. But since these analyzes carry some risk, they are also performed only in
The conception calculator for boys and girls will help you determine the most suitable time to conceive a child of the desired gender based on the date of ovulation.
Pregnancy, future motherhood and fatherhood are some of the most important events in life. After receiving news about the imminent replenishment of parents, the question always torments: who will be born? Girl or boy? Since ancient times, there are many methods and acceptances for sex determination, but none of them guarantees a 100% result.
How to conceive a boy or girl?
It has been proven by science that the sex of the baby is programmed at the moment of conception. The fact is that both men and women have two chromosomes. In men, this is the Y chromosome and the X chromosome, in women - 2 X chromosomes. The sex of the child depends on the chromosome of the man, on whether X or Y will fertilize. Although a man's body produces approximately the same number of X and Y chromosomes, there is still a chance of conceiving a child of the desired gender.
The body of any healthy woman is designed in such a way that conception can occur only on certain days of the month. As you know, a woman's menstrual cycle has a strictly individual period, it ranges from 25 to 35 days. Around the middle of the cycle, ovulation occurs, that is, the release of an egg from the ovary. Pregnancy will take place if a meeting with a male sperm cell occurs during ovulation.
Gender of the child by date of conception, day of ovulation and conception
A woman's menstrual cycle is 28 days, the date of the beginning of the last menstrual period is May 31. Thus, its cycle in the current month is from May 31 to June 27. The estimated date of ovulation in this case is June 13th. The chances of getting pregnant are high if you make love between 4 days before ovulation and 2 days after, that is, between June 9 and 15.
It has already been proven by science that sperm with a Y chromosome (so-called male) move faster than sperm with an X chromosome (female). Although male cells reach their target (eggs) faster, they die faster. Female cells are slower in this respect, but more tenacious.
How to conceive a boy? To become pregnant with a boy, intercourse must be arranged exactly on the day of ovulation or within a few hours after it.
How to conceive a girl? The best way to get pregnant with a girl is to have intercourse the day before ovulation.
An example of calculation for the same woman:
With ovulation on June 13, to increase the chances of giving birth to a boy, sex should be directly on the day of ovulation and a little later, that is, June 13 and 14. In order to get pregnant with a girl, sex must be on June 11 or 12.
It is important to understand that although this calculation has been scientifically proven, it is impossible to guarantee the exact result, because any female body is unique.
To start calculating the determination of the sex of the future baby, you need to fill out a calculator form.
Read about the method below.
How to use the calculator
- Fill in all the fields with the original data. There are hints for the "Length of Menstrual Cycle" and "Length of Luteal Phase" fields, which can be viewed by hovering the mouse cursor over "What is this?" next to the input field.
- The script will automatically calculate and display you a conception calendar, in which you will see favorable and unfavorable dates for conceiving a baby. When you hover your mouse over an auspicious day, you can see who is more likely to (by this method) you will be conceived at this time.
About the method of planning the sex of the child by ovulation
This is a very common method among expectant mothers.
It is based on the data that spermatozoa carrying Y-chromosomes (when fertilized, a boy is obtained) are more mobile / fast, but less "tenacious". And spermatozoa with X chromosomes, on the contrary, are less mobile, but more resistant to unfavorable external factors.
Hence, conceive girl more likely to be if intercourse (PA) perform 3-4 days before ovulation (release of the egg). Indeed, according to the fact that is fundamental to the method, it is mainly the “tenacious” X-spermatozoa that will be able to “survive” until that moment.
A boy more likely to be born if PA occurs the day before ovulation or exactly on that day (motile spermatozoa with Y chromosomes "on board" have a greater chance of being the first to reach an egg ready for fertilization).
