If you feel your stomach move in the first month of pregnancy, it is clinically unlikely to be fetal movement, and is likely to be caused by fluttering of the abdominal aorta, which fluctuates in a regular manner and is consistent with the pulsation of the pulse. If you are a primigravida, you are relatively insensitive to fetal movement, and you will not consciously feel fetal movement until you are about five months pregnant. If a woman in labor is relatively more sensitive to fetal movement, she will be aware of fetal movement in the fourth month of pregnancy. Fetal movement is an important sign of fetal survival in the uterus, if you feel your stomach moving in the first month of pregnancy, and there is no way for you to distinguish whether it is the abdominal aortic pulsation or not, it is recommended to go to the hospital to do the necessary tests, and you can do ultrasound to understand the development of the fetus in the uterus.
