Usually, you will start to feel fetal movement in the fourth month of pregnancy, and the first-time mothers will feel it later than menstruating mothers. Fetal movement refers to the movement of the fetus in the uterus and can usually be felt between 18-20 weeks of pregnancy. As the months of pregnancy increase, fetal movement will become more and more obvious. When the fetus is in the pelvis in the late pregnancy, the fetal movement may be smaller. After 28 weeks of pregnancy, the fetal movement will become stronger and more regular, so you can start to self-check the fetal movement from 28 weeks. You can count the fetal movement for one hour in the morning, noon and evening every day, the fetal movement should be between 3 and 5 times per hour, and the fetal movement should be once within 5 minutes continuously. Too much or too little fetal movement is a sign of fetal hypoxia, which needs to be checked and treated in hospital. After 33 weeks of pregnancy, you can check the fetal heart monitoring to know whether the fetus has hypoxia.
