It is normal for the pregnant belly to beat like a pulse, mainly because the abdominal wall veins will feel like a pulse when they are beating. Most people can feel the fluctuation of abdominal wall veins, pregnant women will be more obvious, because the blood volume of pregnant women is relatively more, the blood flow rate is relatively faster, metabolism will be more obvious, especially in the second trimester more obvious. The blood volume is the most, and the pressure on the abdominal wall due to the enlarged uterus in the later stages will lead to the relative protrusion of the abdominal wall veins. If the pulse-like beating of the stomach is felt in the middle or late pregnancy, it may be due to the activity of the fetus in the uterus, which has a regularity. If the regularity changes drastically, it needs to be taken seriously enough and the pregnancy needs to be taken care of with more rest and avoiding strenuous exercise.
