The fetus is not moving because the fetus may not have reached enough months, on the other hand, the fetus may be miscarried, the specific fetal condition should be determined according to the examination results. If the fetus moves less or does not move, it is best to go to the hospital for fetal heart monitoring to see if the fetus is suffering from oxygen deficiency and to confirm the diagnosis before treating the problem. If the fetus does not move while sleeping, some fetuses do not like to move and the fetal movement will be reduced. In the second trimester, when the fetus is in the pelvis, the fetal movement will be limited and the pregnant woman will not feel the fetal movement. As long as the fetal heartbeat is normal and the size of the fetus matches the month of pregnancy, there is no need to be nervous. Sometimes maternal nervousness can also cause reduced fetal movement, but be careful to distinguish it from stillbirth.
