Fetal movement refers to the movement of the fetus in the uterus by reaching and kicking, thus impacting the uterine wall. Usually the fetal movement can be clearly felt after the fourth month of pregnancy, that is, from the fifth month. Post-pelvic fetal movement refers to the fetal movement when the pelvis has opened and the fetus is sliding into the pelvis and is about to leave the mother’s body. At this time there will also be fetal movement, but some people can not feel it or feel it not obvious. Fetal movement is one of the important elements of clinical prenatal fetal monitoring techniques, and the number, speed and intensity of fetal movement can be monitored to assess the safety and security of the fetus. Normal fetal movement indicates good uteroplacental function, adequate oxygen delivery to the fetus, and a healthy fetus in utero. The position of fetal movement is related to the position of the fetus, generally around the belly button is more obvious, as the fetus into the pelvis, the position of the fetus in the uterus will be correspondingly lower, the position of fetal movement will also change. And the frequency of fetal movement will generally decrease accordingly, and the amplitude of fetal movement will also be weakened accordingly. Therefore, if pregnant women do not feel the fetal movement or fetal movement is not obvious, do not worry too much or even anxious, normal wait to welcome the new life can be.
