Does a round belly have to be a girl?

This is not necessarily the case.

There is a folk proverb: "A girl with a round belly gives birth to a boy with a pointed belly". This is a fallacy without any scientific basis.

The shape of the pregnant woman's belly is largely determined by the size of the fetus. Although it is true that boys are heavier than girls at birth, this difference is not enough to make a significant difference between pregnant women's bulging bellies.

In addition, the position of the fetus in the uterus will also affect the shape of the mother's stomach. If the baby's back faces the mother in the womb, the mother's abdomen will be more prominent, whereas if the baby faces the mother in the womb, the abdomen will look flatter. These have nothing to do with the sex of the child.

The most reliable way to determine a child's sex before delivery is either to wait for the fetus to grow to about 13 weeks, or to use villus puncture, or to detect whether there is a unique sequence on the Y chromosome in the mother's blood. If there is, it must be a boy. Anyway, you have to go to the hospital for identification.
