There are many ways to determine the gender of the fetus, but most of them have no scientific basis and cannot be trusted. After women become pregnant, some women give birth before the due date, while some women have reached the due date but have not yet given birth. Therefore, many people believe that most of the births after the due date are girls, and those born before the due date are boys. Is this true? Are all babies born after the due date girls? If the baby is not born after the due date, it is not necessarily a girl. Generally, it is normal for a fetus to be born 2 weeks before or after the due date. A post-term pregnancy is considered overdue if the pregnancy reaches or exceeds 2 weeks of the due date. Even if the placenta and amniotic fluid are normal, delivery may be difficult due to the large fetus and the hard skull, which has nothing to do with the gender of the fetus. Generally speaking, male chromosomes are divided into X and Y, while female chromosomes are only X. When a man and a woman have sex and conceive, if the male X chromosome combines with the female X chromosome, the fetus is a girl; if the male Y chromosome combines with the female X chromosome, the fetus is a boy. It should be said that the sex of the fetus is determined by chromosomes and has nothing to do with the expected date of delivery. Therefore, the statement that the boy or girl can be calculated based on the expected date of delivery lacks scientific basis. The so-called method of calculating the gender of a baby using the due date is as follows: add the pregnant woman's age (in lunar years) + the due date month (in lunar calendar). If the last digit of the resulting number is an odd number, it is a boy; if it is an even number, it is a girl. A. Calculation of expected date of delivery According to medical regulations, the expected date of delivery is calculated from the first day of the last menstrual period. The entire pregnancy period is 280 days, or 10 gestation months (each gestation month is 28 days). Add 9 or subtract 3 from the month of the last menstrual period to get the month of the expected delivery date; add 7 to the day of the last menstrual period to get the day of the expected delivery date. For example: The last menstrual period was on March 4, 2012, the expected date of delivery is 3 + 9 + 12, the date is 4 + 7 + 11, and the expected date of delivery is December 11. (Lunar calendar is November) B. Calculation of the gender of the baby If the pregnant woman was born in 1989, her age (in lunar years) is 24 + the month of delivery (in lunar calendar) 11 = 35, and the last digit is an odd number, which means she is giving birth to a boy. Omens before the birth of a blessed child In fact, some children are very blessed before they go out. There is a saying in China that if a person is blessed, there will be something extraordinary when his mother gives birth to him. The so-called extraordinary may be that his mother encountered some strange things when giving birth to him, or other strange things may happen. Anyway, it is more like that. As for some important figures, their children will be very strange, and Chinese people will not say these things are strange, but will consider them to be auspicious signs, which are a good omen. So basically according to this, there are some people who will be ordinary when they come to this world, which means they were destined not to be hurt in their previous life. |
