Some people believe that by calculating the due date can predict the baby sex. The specific method is to calculate the age of the pregnant woman (imaginary years) and the expected month (lunar calendar) and, if the resulting number of the end of the singular is a boy, if it is an even number is a girl. It is also believed that boys are born "early" and girls are born after their due dates.
Calculation of the expected date of birth of men and women is accurate
Calculation of the expected date of birth of men and women is actually not allowed. The reason for this is that the sex chromosomes are determined by the male chromosome, the male chromosome has X and Y, while the female only has X chromosome, if the male X chromosome and the female X chromosome are combined, the fetus is a girl; if the male Y chromosome and the female X chromosome are combined, the fetus is a boy. Therefore, the sex of the fetus is determined by the chromosomes and has nothing to do with the due date. And the timing of the delivery of the fetus is affected by intrauterine factorsThe most effective way to find out if you have a boy or a girl is through ultrasound.
In the expected date of birth also need to pay attention to some matters:
1, pay attention to fetal movement
Every day pay attention to fetal movement, walk more, or change position.
2, more walking and climbing stairs
More walking and climbing stairs, pay attention to safety, avoid accidents, and also good for the baby.
3, broken water requires immediate medical attention.
4, prepare a good waiting bag for labor and delivery.
In short, the kind of test on the Internet to test the gender of the baby according to the due date calculator is not allowed, and every baby is born to the mother in October, it is recommended that pregnant women do not worry too much about the gender of the fetus.
