Several calculation methods of giving birth to boys and girls

Many families are curious about the sex of the unborn baby and want to know in advance whether the baby is a boy or a girl. Many people talk about many habits, fetal movement, diet and so on. Can make certain judgments in life. Some people say that there are calculation methods, so let's look at several calculation methods for giving birth to boys and girls.

Several calculation methods of giving birth to boys and girls 1, formula calculation method: 68+ lunar month of pregnancy-mother's age at pregnancy =, and the mantissa is single, it is a boy; The mantissa is double. It is a girl. For example, when you are pregnant, it is August of the lunar calendar. When you are pregnant, your mother's nominal age is 27 years old. The calculation method of giving birth to a boy and a girl is 68+8-27=49. As a result, the mantissa is single, which means it is a boy.

2. Cardinality calculation method Cardinality: 49 (unchanged)+lunar month when pregnant-imaginary age of mother when pregnant+19 (unchanged) to get the result, if the result is even, it is a girl, if the result is odd, it is a boy. For example, if you are pregnant in June of the lunar calendar, the nominal pregnancy age is 2 1. 49+6-21+19 = 53 is singular, indicating that it is a boy.

3. Age calculation method: the sum of father's age at pregnancy+mother's age+months of pregnancy (both real numbers), divided by 3, the result is an integer, the odd number is a boy, and the even number or zero is a girl. For example, the pregnant father is 30 years old and the mother is 27 years old, and she is pregnant in June. The calculation method for boys and girls is (30+27+6)/3=2 1. As a result, the mantissa is single, which means it is a boy.

4. Date calculation method: the date of birth of prospective father (year+month+day)+the date of birth of expectant mother (year+month+day)+the date of pregnancy of mother (lunar month)-number 19=, depending on the mantissa of the last number. If it is odd, it means having a boy; if it is even, it means having a girl. For example: male 1989 born on September 5th, female 1989+05438+00+9 born on September 9th, male and female pregnant in July, {(89+9+15)+(89+/kloc-)

Folk method to predict fetal sex 1. Judging from the shape of pregnant women's stomachs, pregnant women's stomachs are pointed and convex, and they will give birth to boys; A round belly gives birth to a girl. In fact, the shape of the pregnant woman's belly has nothing to do with the sex of the fetus.

2. Changes in the taste of pregnant women: Some people think that if the taste of pregnant women is different from that of the previous fetus, the sex of the fetus will also change. In fact, pregnant women like to eat sour and sweet, which has nothing to do with the sex of the fetus.

3. Observe the changes in the appearance and skin of pregnant women: if the appearance of pregnant women becomes beautiful and the skin becomes smooth, it is possible to have girls; On the other hand, if the appearance becomes ugly, the skin becomes rough, and even the face is covered with acne, it is possible to have a boy. Many people believe this statement, but it turns out that the credibility is not high.

4. The speed of fetal heart: It is generally believed that if the fetal heart is strong and slow, it is more likely that the fetus is a boy; On the other hand, it is a girl. This method of guessing the sex of the fetus has a high probability of error.
