The main characteristics of being pregnant with a girl include enlarged belly, rounded belly, high fetal heart rate, etc. However, these are all folklore and have no scientific basis. In fact, the gender of the fetus is determined by its chromosomes and has nothing to do with the shape of the pregnant woman\’s belly, fetal heart rate, degree of morning sickness, etc. Therefore, expectant mothers do not need to pay too much attention to the gender of the fetus during pregnancy. They only need to maintain healthy living habits and undergo regular prenatal checkups to ensure the safety of mother and baby.
