Without exception, all future parents want to know as early as possible what gender their child will be born to. Thanks to ultrasound examination (ultrasound), this can be found out not earlier than the second trimester, and at such early date mistakes often happen. All that remains for parents is only to rely on scientific and folk methods in order to find out already 7-8 months before giving birth who will be born - a girl or a boy. Who will have a mother and father, what methods of calculating sex exist and how reliable they are, we will tell in our article. Here we will present an extensive list of signs that will help to find out the gender of the unborn baby at home.
Ultrasonography
The most famous and most common method of determining the sex of a child today is ultrasound. Thanks to ultrasound, the doctor and the expectant mother can monitor how well the pregnancy is proceeding, make sure that the fetus does not have developmental abnormalities, and at the same time find out the sex of the child. In many Russian centers for ultrasound diagnostics, this service is paid additionally, since the state of the fetus is still put forward in the first place, and not its gender.
You can find out on an ultrasound who will be a boy or a girl at 15-16 weeks of pregnancy. However, mistakes often occur during this period. An ultrasound scan done for a period of 18-25 weeks gives a more accurate result, but it cannot be called 100% correct. More than once there were cases when a woman, being sure from 20 weeks that she was wearing a girl under her heart, gave birth to a healthy boy, and vice versa. The result is influenced by the position of the fetus, and the state of the ultrasound apparatus, and the qualifications of the doctor who conducts the study.
Fetal heartbeat
This theory is based on the fact that boys and girls have different heart rates in the womb. According to this technique, if a baby's heart beats less than 140 beats per minute, then a boy will most likely be born. In girls, the heart rate is always equal to or higher than this value. This method is quite effective in assuming who will be born to a woman - a girl or a boy. Who it really will be, you can find out only in the hospital.
It is not possible to calculate the exact number of beats per minute at home. But a sign associated with the heartbeat of a child has already appeared among the people. It is based on the fact that if the baby's heart beats faster, then we should expect the birth of a girl, and if slower, then a boy will be born.
DNA analysis
Starting from the 5th week of pregnancy, you can find out the sex of the baby by the DNA of the fetus found in the mother's blood. This analysis is in many ways even preferable to ultrasound, since already at a period of 8 weeks its effectiveness is 99.9%.
To perform the analysis in a special laboratory, blood is taken from the mother. The analysis itself is based on the fact that if, as a result of a blood test, a Y chromosome is found in it, this means that a woman is carrying a boy. If, during the analysis, this chromosome is not found, then it is worth preparing for the birth of a girl.
The technique is very effective in determining whether the mother will be born - a girl or a boy. Who it will be becomes clear already in the first month of pregnancy. At this time, the baby's cells appear in the mother's blood. If a woman is carrying a boy, then Y-chromosomes appear in her blood, which can only be detected by a highly sensitive method in the laboratory.
What will the test show: who will be - a boy or a girl?
It is not at all necessary to wait for an ultrasound examination in the second trimester to determine which gender is under the mother's heart. And even DNA analysis is not required. With an accuracy of 99%, you can find out the sex of the baby using the first morning urine.
Today, pharmacies sell special tests that allow you to find out if a woman will have a son or daughter. The set of such a pharmacy test includes: a container for collecting urine, a special dispenser for liquid and a test directly with a catalyst inside.
How do you know who will be a boy or a girl on the test from the pharmacy?
You need to follow these steps:
- Collect the first morning urine in a sterile container.
- Fill the dispenser with urine up to the 20 ml mark.
- Insert the dispenser into the hole in the dough and pour all the liquid into it.
- Mix the contents of the dough with gentle clockwise movements and place it on the table.
- After 5 minutes, you can check the results according to the instructions on the test.
The reliability of the test is one of the highest after ultrasound and DNA analysis.
Homemade baking soda test
Among pregnant women, another test is popular, which is performed at home using the tools available in every home. Thanks to this technique, you can find out who will be - a boy or a girl - without an ultrasound. What is the essence of a home test?
You will need two sterile containers for the test. In one you will need to collect the first morning urine, and in the other pour baking soda (1 teaspoon). Further, all actions are performed according to the principle of a pharmacy test. Prepared urine is poured into a container with soda. The result of the test can be judged by the reaction. If the soda begins to fizzle, as when reacting with vinegar, then the woman is carrying a boy. With a girl, the reaction with soda will be zero. Urine won't work on baking soda.
Ancient chinese table
Research proves that the ancient Chinese table, which was compiled more than 700 years ago, is 90% correct in determining the sex of the child, if used correctly. The sex of the child is predicted based on the month of conception and the age of the mother. Knowing the exact month of conception, you can easily find out who will be - a boy or a girl.
The table allows you to calculate the sex of the child that the woman is carrying, up to the 45-year-old mother. Age is in the right column, and the month of conception is in the top line. At the intersection of the values, the predicted gender of the child is indicated: boy or girl (boy or girl).
Blood renewal
The blood renewal technique is used by future parents quite often, since it is one of the most effective and efficient. It is based on the fact that in both men and women, the blood is systematically renewed. However, the frequency of this phenomenon is different for both sexes.
If a woman's blood is renewed after four years, then in a man it happens a little more often - every three years. It is quite simple to calculate who will be a boy or a girl using this technique. It is necessary to calculate which of the future parents has fresh blood. If the renewal of blood later occurred in a woman, then a girl will be born, and if a man, then a boy will appear. The calculation must take into account possible surgery, trauma with large blood loss or donation. All this will contribute to unscheduled blood renewal.
You can check the technique using an example. If a woman was 30 years old at the time of conception, then her blood was renewed for the last time in 28 years, that is, 2 years ago. Moreover, the man's age is 34 years. His blood was last renewed at 33 years old, that is, 1 year ago. In this case, the male blood is fresher, which means that the couple will have a boy.
Who will be - boy or girl: blood group table
The following sex determination system is based on the blood group of the parents. It is not 100% reliable, but it is quite popular among expectant mothers and fathers.
It is possible to predict the sex of the child even at the planning stage, before the pregnancy occurs. Who will be - a boy or a girl, you can calculate, knowing the blood group of the mother and father. At the intersection of the two indicated values, the answer to the question is found.
Numerology
The science of numerology is engaged in determining the sex of a child. To calculate who will be a boy or a girl, it is necessary to translate all letters into numbers using the following table.
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
| A | B | V | G | D | E | Yo | F | Z |
| AND | Th | TO | L | M | N | O | P | R |
| WITH | T | Have | F | X | C | H | SCH | SCH |
| B | S | B | E | YU | I AM |
According to the numerological table, it is necessary to make the appropriate calculations to determine the sex of the child. To do this, you need to know the last name and full name of the baby's dad, maiden name and full name of the mother, month of conception. With the help of the table, all the letters in the words are transformed into numbers, added and divided by 7. The sex of the child is determined by the number obtained as a result. If the result is an even number, this means that there will be a girl, and if an odd number, then we should expect the birth of a boy.
How do you know who will be - a boy or a girl? Let's take a look at an example of calculations.
Father's surname and full name: Kuzin Sergey - 3 + 3 + 9 + 1 + 6 + 1 + 6 + 9 + 4 + 6 + 2 = 50
Mother's maiden name and first name: Book of Eugene - 3 + 6 + 1 + 4 + 1 + 6 + 3 + 4 + 6 + 6 + 1 + 6 = 47
Month of conception: February - 4 + 6 + 3 + 1 + 4 + 1 = 19
Calculation of results: 50 + 47 + 19 = 116.
Divide the resulting number by 7: 116/7 = 16.57. We discard the numbers after the decimal point and get the number 16. This means that the couple is expecting the birth of a girl.
Divination with a ring
Fortune-telling to determine the sex of the future baby is no less popular among pregnant women. One of them is based on the use of a wedding ring (namely, an engagement ring and no other). By how the ring suspended on a string will move, you can find out who will be - a girl or a boy.
Who will be, what gender the child will be born, according to this method, you can find out as follows:
- Remove the wedding ring from the ring finger of your right hand and tie a thick thread about 30 cm long to it.
- A pregnant woman needs to take a horizontal position.
- Take a pendulum made of thread and a ring and hold it over the belly of the pregnant woman for 30 seconds.
- If the pendulum moves back and forth, it means that the woman will have a girl. If the pendulum makes circular movements, the pregnant woman should prepare for the birth of her son.
Folk omens
Pregnant women always come across folk methods of sex determination, regardless of whether they are interested in them themselves or some kind neighbor will inadvertently prompt. A variety of signs are associated with the definition of gender.
Who will be - a boy or a girl, you can find out by the following signs:
- if the expectant mother wants something sweet, this means that she carries a daughter under her heart, and if she wants something sour, then most likely a son will be born;
- if the expectant mother always wants to sleep, then a girl will be born, and if, on the contrary, she is full of strength and energy, then a boy should be expected;
- if, when looking at a pregnant woman from behind, you can clearly see the waist, then she will have a boy;
- boys in the mother's belly are usually more active than girls;
- when carrying a girl, women more often have acne, stretch marks on the skin, and become brittle nails;
- if the belly is in the shape of a circle, then there will be a girl, and his tummy is sharp, then there will be a boy.
Despite the effectiveness of many of the presented methods, you should not trust them 100%, because the sex of the child can be found out for sure only in the hospital.
Many people in the modern world are used to planning their future. The birth of a baby is no exception. More and more often, future parents want to know in advance who will be born to them. One of the popular research methods is to calculate the sex of the child by How much can you believe this method? This is what this article will tell you about. You will learn how to calculate the sex of the child by blood renewal. You can also find out the features of this process.
Blood renewal
Normally, each person has this process. In addition to blood, mucous membranes and skin are also renewed. does not require outside intervention. It happens on its own.
The timing of the described process is set individually for a man and a woman. For example, males undergo this procedure once every four years. Renewal occurs more frequently among girls and women. Their blood is cleansed every three years.
Calculation of the sex of the child by blood renewal
The calculation can be done in two ways. The first involves dividing the age at which a person was during the period of conception by the required number. The second one starts counting directly from the date of birth. However, it is less convenient. This is due to the fact that many phenomena can occur during life that affect the timing of blood renewal.
How to calculate the sex of a child using blood renewal? When using the first method, you need to find out the total number of years of the mother and divide the resulting number by three. Over the years, fathers do the same. However, the divisor in this case is four. The results obtained are compared. Whose blood turned out to be younger, the child of that sex will be born to this couple.
How to calculate the sex of a child using another method for renewing blood? In this case, you take the woman's year of birth and add 3 to it, then 3 more, and so on until the moment of conception. You act the same way with your father's age. Only in this case you need to add 4.
Calculation example
- Option one. Mother at the time of conception, for example, 26 years old. This number must be divided by 3. The result is 8.7. The father's age at this moment is 27 years old. Divide these years by 4 to get 6.8. Compare the leftovers. The mother's blood is younger. Hence, there will be a girl.
- Second way. The woman was born in 1989. Her blood will renew in the following periods: 1992, 1995, 1998, 2001, 2004, 2007, 2010, 2013, 2016. The man was born in 1986. His blood will undergo renewal in 1990, 1994, 1998, 2002, 2006, 2010 and 2014. If the child will be conceived in 2014, the couple will have a boy.
Special cases
How to find out the sex of the child by renewing the blood of the parents, if they were born on the same day? Experts still cannot find the answer to this question. Some scientists say that in such a situation there is a big one. Other scientists argue that two babies are born at the same time when the remains are equal.
In any case, in such a situation, as in other cases, it is necessary to take into account external factors that can affect the renewal of blood before calculating the sex of the child by renewing the blood of the parents.
The popularity of the described method and its reliability
Researchers say that currently there are many different ways to determine the gender of the planned baby. These include all kinds of tables and pentagrams, online applications and calculations. The most popular among them is the ancient Chinese table and the method of blood renewal.
Despite the acquired popularity, experts say that the effectiveness of this method is rather low. So, some scientists call the probability of an accurate hit 2%. Others are talking about 50%. What is the real situation?
Can you believe the method described above?
Determining the sex of a child by renewing the parents' blood is quite simple. However, this does not guarantee you will receive accurate data. In most cases, a good match is just a coincidence. This fact is explained as follows.
During fertilization, two cells merge: the male and female gametes. The ovum contains only the sperm, but it is more interestingly arranged. It may contain a set of x-chromosomes. In this case, the couple will have a girl. When a male cell has one play-chromosome in its composition, a boy is born in the near future. Based on these data, we can conclude that human blood has absolutely no effect on the sex of the unborn baby. All ways are recognized as simple entertainment, rather than truthful information.
The opinion of married couples
Many families, who were told how to calculate the sex of a child by blood renewal, were able to plan ahead for the birth of a boy or girl. They just made a calculation and found out in what years and months they will have a baby of one sex or another. These couples speak extremely positively about the described method.
Most of the individuals tested refuted the above theory. Simple calculations did not confirm the birth of a child of a particular gender. It is on this information that scientists rely, citing the percentage of positive outcomes of the calculation.
The necessary information
Before trying to renew blood, you must take into account all the data. So, a change in the bloodstream can occur not only at the above intervals. This process is sometimes also influenced by external factors.
Premature renewal of the bed occurs during childbirth, operations, with severe blood loss, various injuries, treatment, blood and plasma transfusions, as well as among donors. It is from this moment that a new countdown begins. Many couples do not take this information into account. That is why they do not agree on the data obtained and the actual outcome of events.
A short summary of the article or conclusion
Now you probably know by updating the blood of his parents correctly. When choosing this method of calculation, always take into account the complete information about both partners. Otherwise, the data may turn out to be incorrect.
It is absolutely possible to find out the sex of the unborn baby with absolute certainty only during an ultrasound examination carried out at 20 weeks of pregnancy or later. However, in this case, the assumption may be wrong. Do not trust the described calculation method too much. I wish you success and fulfillment of your desires!
In this article, we discuss the pregnancy calendar. You will learn how to correctly count the weeks of pregnancy according to the calendar, how to determine the expected date of birth and the gender of the baby. We will tell you how to use the pregnancy weight gain calendar and provide a variety of calculation schemes.
The weekly pregnancy calendar is an important tool that is designed to help expectant mothers while waiting for the baby. With its help, you can calculate the expected date of birth, monitor the course of pregnancy in accordance with gynecological standards, track important stages and events during the waiting period for the baby.
With the help of the pregnancy development calendar by weeks, the expectant mother will find out at what stage of development her baby is, what skills she already has, and what he needs most of all at this moment... This tool is also used to calculate the sex of the child.
There are many services on the Internet that provide an online pregnancy calendar. With this tool, the expectant mother can always have at hand all the necessary information about the course of pregnancy in her gadget, without leaving home.
Scheme for calculating the date of birth
A healthy pregnancy lasts 38 to 42 weeks... Different calculation methods are used to determine the expected due date. Any of these are not 100% accurate. The optimal deviation in calculating the PDD (estimated date of birth) is 10 days before and after the appointed date.
There are 4 ways to determine the expected due date:
- obstetric - by the date of the last menstruation;
- palpation - after the first examination by a gynecologist;
- embryonic - by the date of ovulation;
- ultrasonic - according to the results of ultrasound.
This is how the baby develops in the womb of maater
According to the obstetric calendar of pregnancy, the expected date of birth is calculated, starting from the extreme menstruation. To do this, use the Negele formula, according to which to calculate the PDR from the first day of the last critical days, it is necessary to subtract three months and add 7 days. In other words, exactly 40 weeks are added to the first day of the last menstruation.
After the first visit to the antenatal clinic and examination on the chair, the obstetrician-gynecologist determines the approximate gestational age. The specialist measures the size of the uterus, the height of its bottom, the size of the fetus and the volume of the abdomen. Based on these indicators, the doctor calculates the expected date of delivery.
According to the embryonic method for calculating the expected date of birth, the starting point is the date of ovulation, i.e. day of release of the egg from the ovary. This period is considered the most favorable for conception. The ovulation pregnancy calendar is calculated by adding 38 weeks to the ovulation date. With a cycle of 28 days, it occurs 2 weeks after the onset of menstruation.
To determine the PDR, a pregnancy calendar is also used by the date of conception.... It is often confused with the previous calculation method, but there is a slight difference between the two. Fertilization of the egg does not always take place day in and day out with ovulation. Sperm cells remain viable in the vagina for 1-3 days after intercourse, so the fertilization process itself may occur a couple of days later.
The ultrasound method for determining the expected date of birth is considered the most accurate. The first screening is carried out at 12-13 weeks. This study allows you to calculate the PDR with an accuracy of 1-3 days.
Scheme for calculating the sex of the child
There are many ways to calculate the sex of a child. Let's consider the most common ones. To determine the sex of the child according to the pregnancy calendar, it is necessary to add the day of the month in which the last menstruation and the age of the mother were. An even number means that a girl will be born, an odd number means a boy.
To calculate by the pregnancy calendar, a girl or boy will be born, you can use the following formula: (3 + BM + MZ + MR) / 2, where VM is the mother's age, MZ is the month of conception, MR is the month of birth of the mother. If the calculations result in an even number, a boy will be born; if an odd number, a girl will be born.
To determine the sex of the child, the blood group of the parents is used. Different Rh factors of the father and mother indicate a greater likelihood of a boy. Here is a table for calculating the sex of the child based on the blood groups of the parents.
| Blood type | Father | |||
| Mother | 1 | 2 | 3 | 4 |
| 1 | D | M | D | M |
| 2 | M | D | M | D |
| 3 | D | M | M | M |
| 4 | M | D | M | M |
According to ancient Chinese tradition, a table by the age of the mother according to the pregnancy calendar is used to determine the sex of the child. For the calculation, it is necessary to compare the mother's age at the time of conception and the month of fertilization.

Another popular calculation technique is the Japanese table of the sex of the child according to the pregnancy calendar. According to this method, you first need to compare the months of birth of both parents and find the number at the intersection of these dates.
| Woman's birth month | Month of birth of a man | |||||||||||
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | |

| December | 4 | 8 | 12 | 4 | 8 | 12 | 4 | 8 | 12 | 4 | 8 | 12 |
After the number has been determined, it must be compared with the month of conception of the child. At the intersection of these indicators, the table shows the pluses. Their number symbolizes the greater or lesser likelihood of conceiving a boy or girl.

You have learned how to calculate the date of birth and the gender of the baby using the weekly pregnancy calendar. Now let's talk about controlling weight gain during pregnancy.
Pregnancy weight gain calendar
Weight gain during pregnancy is individual for each woman, but despite this, there are general norms for this indicator, which speak of a healthy pregnancy or some deviations. A weight gain calendar is used for control. This tool builds on the mother's baseline weight prior to conception and provides nutritional and weight gain recommendations for each week of pregnancy.
Strict adherence to a weight gain calendar will help avoid problems such as being overweight, which can cause a number of disorders during pregnancy and postpartum period... We are talking about edema, increased stress on internal organs, disorders of the cardiovascular system, fetal hypoxia, and a prolonged period of rehabilitation after childbirth.
On average, during pregnancy, a woman gains from 9 to 14 kg of weight, while waiting for twins - from 16 to 21 kg. During the first trimester, the weight does not change much, the weight gain is up to 2 kg. In the second, the woman is gaining about 300 grams. per week, in the third - 400 gr. over the same period.
There are three groups into which women are conventionally divided, based on the body mass index (BMI):
- Group 1 - thin women, BMI - up to 19.8;
- Group 2 - ladies of average build with BMI from 19.8 to 26;
- Group 3 - obese women, BMI - from 26.
To calculate the body mass index, you must divide the woman's original weight before pregnancy by the square of her height in meters. For example, with a weight of 58 kg and a height of 166 cm
(1.66 m) BMI will be 21.
Knowing the body mass index, you can compare the indicators of weight gain during pregnancy using the table below.

About who "lives" in the stomach, a boy or a girl, can tell the date of the last menstruation. Today, the method of calculating the sex of a baby by menstruation is quite popular.
Determining the sex of the child by the date of the last menstruation
How to determine the gender of a child using the date of the last period? To do this, girls need to know the two main days on which menstruation began and ended.
To help expectant mothers - a table with the help of which, in the event of pregnancy, they will determine the sex of the child by the last menstruation. This calendar allows you to make convenient calculations in the future, already during pregnancy.
How to find out the gender of the child by the date of the last menstruation?
Method 1.
To calculate, you need to know the days when your period started and ended. This will allow you to easily determine the month in which the baby was conceived. By the way, such data will also be required by an obstetrician-gynecologist, to whom the expectant mother will go to register.To calculate the sex of a child by the date of the last menstruation, you need to make simple calculations. Let's imagine that the baby was conceived in October, that is, in the 10th month (we understood this by the date of the last menstruation), and the age of the expectant mother is 24 years. Further, according to the formula, we should add the obtained values and add one to them. If you get an even number, wait for a girl, if an odd number, wait for a boy. That is, in our case it turns out: 10 + 24 = 34 + 1 = 35. Since the number is odd, a boy will be born.
Method 2.
If you do not know how to calculate the sex of an unborn child by menstruation, use very real scientific data. Every girl knows what ovulation is. If you keep your own calendar of the monthly cycle, you can calculate the gender of the child with a high degree of probability.
To do this, it is necessary to compile a cycle table for several months and measure the basal temperature every day. Data should be plotted on a graph.
After you collect all the information, you can determine the exact period of ovulation. It falls at the peak values of the basal temperature, which rises to 37 degrees approximately in the middle of the cycle, and then decreases.
Next, we go directly to determining the sex of the child. The most suitable days for conception are the days of ovulation: it is at this time that the egg fully matures. Spermatozoa, which contain female chromosomes, are highly survivable and can fertilize an egg within 5-6 days. Sperm with male chromosomes are less tenacious, but more mobile. They die within 1-2 days.
For those who want to conceive a girl, the optimal period for having sex is 5-6 days before ovulation. Parents who dream of an heir should conceive either the day before ovulation, or during it.
By the way, determining the sex of a child by the date of the last menstruation can be carried out using the online ovulation table, which is available on various Internet resources. If you don't want to keep a paper calendar, you can use this table.
Thus, it is quite possible to calculate the sex of the baby by the date of the last menstruation, although this method will not give you a 100% result. But, judging by the reviews of many girls, the probability of this method is quite high, so you can safely use it. Believe it or not the results obtained is up to you. In any case, the most important thing is that the child develops and grows well, and who he will be - a boy or a girl, this is not so important.
