Generally speaking, fetal movement occurs around 16 to 20 weeks of pregnancy, of course, the specific situation still varies from person to person, because the feeling of fetal movement and the pregnant mother’s physical condition is related to a certain extent. For thin pregnant women, abdominal fat is relatively thin, may feel fetal movement relatively early, generally around 16 weeks can feel fetal movement. For the fat pregnant women, due to the abdominal fat layer itself is thicker, so the time to feel the fetal movement will be relatively late, need to be around 20 weeks to feel the fetal movement. Under normal circumstances 16 to 20 weeks of pregnancy, most pregnant women can feel the occurrence of fetal movement, the beginning of the fetal movement may be very slight, amplitude is not large, without careful observation is not necessarily be found. As the weeks of pregnancy increase and the size of the fetus increases, the amplitude will become larger and larger, fetal movement will become more and more obvious. If a pregnant woman does not feel fetal movement after 20 weeks, it is recommended to go to the hospital and under the guidance of the doctor for relevant examinations.
