There is no scientific basis for this statement that the pregnant woman is a boy and a girl. If the pregnant belly and lower abdomen bulge are obvious, it is pregnant. If the fetal position is lower, the lower abdomen bulge is pregnant, which is related to the shape of the pregnant woman and many factors, such as the voice of the pregnant woman, laparoscopic surgery, the shape of the pelvis and the thickness of the endometrium. Therefore, this statement is uncertain.
