If a pregnant woman appears to have a smaller stomach in the morning than at night, it should be related to the amount of stomach contents. In the morning, after waking up, the food in the stomach after a night of digestion and absorption, the stomach is basically emptied, the stomach emptied to reduce the squeeze on the abdomen enlargement of the uterus, so the abdomen stretch space is larger, so it looks smaller. At night because just had dinner, more food in the stomach, will produce a certain pressure on the uterus, so it seems that the belly protrudes more obvious, appear larger. This is just an illusion. In fact, the size of a pregnant woman’s stomach during pregnancy is mainly related to the size of the fetus and the amount of amniotic fluid, the fatness of the pregnant woman and the size of her pelvis, but not too much to do with other factors. If the same pregnant woman, in the same time, the size of the belly should be relatively fixed, the morning and night will not change too much, there is no need to dwell.
