There is no so-called special difference between carrying a boy and carrying a girl; the sex is determined by the chromosomes of the fetus. During pregnancy, a series of physiological changes occur in the mother’s systems and organs, and pregnant women may experience symptoms such as nausea, vomiting, back pain and lower limb edema, which are unrelated to whether they are pregnant with a boy or a girl. The sex of the fetus is determined at the time of formation of the fertilized egg union and is related to the type of chromosome. Any claim that there is a specific manifestation of the birth of a boy or a girl is unreliable. Therefore, the birth of a boy or girl is the same, do not believe in rumors, and you need to undergo regular obstetric examinations after pregnancy to avoid adverse pregnancy outcomes.
