Because people are very curious, many pregnant women will want to know whether their baby is a boy or a girl because of their strong curiosity during pregnancy. However, due to the relevant policies, pregnant women can't know the sex of the fetus in their stomachs through hospitals, so they can only guess the sex of the fetus through some indigenous methods. Is it accurate to measure the birth of boys and girls by indigenous methods?

This is the most accurate folk method to test the accuracy of boys and girls. Mothers who have given birth will identify and verify their accuracy, and pregnant mothers will be used as entertainment reference.

1, face, heart-to-heart, giving birth to a son or a daughter, can also be seen from several characteristics of face. From a male point of view, if the left, the first child has a greater chance of giving birth to a boy, if the right, the first child has a greater chance of giving birth to a girl. Judging from the eyebrows. Men with thick eyebrows are more likely to have boys, and vice versa.

2. (1) Formula: 7749, ask when there is sound, subtract the birth mother's age, and add 19.

(2) Algorithm: 49+ pregnant month (solar calendar, that is, the date of the month we usually say)-the age of the mother when she was pregnant+19=XX.

(3) Result: Usually the result is two digits. At this time, we just look at whether the single digits are singular or even. If it is singular, such as 53, it means boy. If the single digit is two digits, such as 54, it means that it is a girl.

3, B-ultrasound to identify male treasures and female treasures

When doing B-ultrasound, the doctor will look at the left and right thighs from under the buttocks. If you look closely, you will find a "mysterious little bump" in the picture, which is a boy, and vice versa.

The most accurate way to test boys and girls is 1. By observing the shape of pregnant women's bellies, we know that they are boys and girls-pregnant women's bellies are sharp and convex, and they are boys and babies; Round belly, pregnant with a baby girl. The position of the fetus is active, and there is no necessary relationship between the shape of the pregnant woman's stomach and the sex of the fetus. The shape of the pregnant woman's belly is largely determined by the size of the fetus and the posture of the fetus in the uterus. The average weight of male fetuses will exceed that of female fetuses, but this difference is not enough to clearly distinguish pregnant women's bulging stomachs. The posture of the fetus will also determine the shape of the pregnant woman's stomach. If the fetus faces the mother in the womb, the pregnant woman's stomach will be more prominent; On the contrary, if the fetus faces the mother in the womb, it will make the abdomen flatter.

2. According to the four-dimensional color Doppler ultrasound after six months, as long as the baby's posture is positive, it is not a back, it is a man or a woman. There is usually "bilateral renal pelvis separation", and 90% are boys; If it is "no obvious separation of bilateral renal pelvis", then 95% are girls. There is also a saying that there are two lines on the far right of the color Doppler ultrasound film, which are composed of English letters and numbers. The first line is the date and the second line is the time. If the first line starts with m, it is male, if it starts with f, it is female, and the second line starts with t, which means time.
