The pregnant woman’s belly is pointed or round, mainly related to the size of the fetus, fetal position, pregnant woman’s body shape, pelvic shape, spine shape and abdominal muscle thickness. Common reasons are as follows: 1, the size of the fetus: the shape of the pregnant woman’s belly is usually determined by the size of the fetus, if the fetus is small, the pregnant woman’s belly will look more pointed. If the fetus is larger, the pregnant woman’s belly will be more round; 2, fetal position: if the fetus is facing the mother, the pregnant woman’s belly may be more convex, and some pregnant women may look more pointed. If the fetus is facing the mother, the pregnant woman’s belly may look smaller, not so pregnant; 3, pregnant women’s body type: if the pregnant woman is thin, the fetus gradually grows lateral no room to grow, can only be forward, the belly will look more pointed. If the body type is more fat pregnant women, more likely to grow laterally, vertically, the abdomen is not so protruding, not so pointed, the overall hair round; 4, pelvic shape: if the pregnant woman’s pelvis is shallow or narrow, easy to show pregnant, resulting in the appearance of the belly pointed. If the pelvis is deeper or wider, it is not easy to show pregnancy, it looks round; 5, the shape of the spine: if the lumbar vertebrae of pregnant women are obviously convex, the sacral vertebrae will be convex, the uterus will be convex forward and look pointed belly. If the lumbar vertebrae are not obviously convex, the uterus will not be pushed forward, the belly is round; 6, abdominal muscle thickness: if the pregnant woman’s abdominal muscles are less, the ability to withstand the pressure of the uterus is weaker, easy to convexity, looks more pointed. If the pregnant woman’s abdominal muscles are thick and strong, the belly is rounder.
