No fetal movement at 39 weeks of pregnancy has nothing to do with inactivity and can be caused by fetal sleep cycles, fetal distress, etc.
Fetal movement refers to the body movement of the fetus, most pregnant women can consciously feel the fetal movement at about 20 weeks of pregnancy, and after 28 weeks of pregnancy, fetal movement counting should be carried out to understand the intrauterine condition of the fetus. The absence of fetal movement at 39 weeks of pregnancy is not directly related to whether the pregnant woman is exercising or not. It may be caused by being in the fetal sleep cycle or fetal distress.
Normal fetal movement count is ≥ 10 times / 2 hours, fetal sleep cycle usually lasts 20 to 40 minutes, but 39 weeks pregnant without fetal movement, ultrasound, fetal heart monitoring and other tests can be carried out to assess the intrauterine status of the fetus, the general situation is good can be continued under the guidance of the doctor to stay in labor, but the examination suggests that fetal distress needs to be terminated in a timely manner.
39 weeks of pregnancy without fetal movement need to go to the hospital to find out the cause, and actively deal with.
