The last menstrual period is seen as a boy and a girl

49 + lunar month of the woman's last menstrual period - the woman's virtual age at the time of pregnancy + 19 = result, the result is a singular number of boys, and the result is an even number of girls. This formula is derived according to the formula, the specific formula is: seven seven forty-nine, ask the mother when there is, subtract the mother's birth age, and add nineteen!

For example, if the lunar month of a woman's last menstrual period is November, and the imaginary age of pregnancy is 28 years old, then the specific equation is: 49 + 11 - 28 + 19 = 51, and the result is an odd number to give birth to a boy.This formula is based on a formula circulated among the people, which has not been clinically confirmed by medical science, and its results are not accurate.

The sex of the baby is determined by the sex chromosomes of the male, the X chromosome sperm gives birth to a girl, and the Y chromosome sperm gives birth to a boy, so to understand the sex of the baby, you need to know the baby's sex chromosomes or external genitalia. Clinically, B ultrasound, maternal DNA blood drawing and other methods are generally used to determine the sex of the baby, but non-medical gender identification is prohibited in China, unless there is a special genetic disease. Therefore, whether you have a boy or a girl, the health of the baby is the most important.
