Frequent fetal movement at 37 weeks is a sign of fetal hypoxia in the uterus, which is abnormal. It is recommended to consult a doctor in time to clarify the cause and to make targeted treatment according to the doctor’s advice. After 37 weeks of pregnancy, the fetus has mostly entered the pelvis. As the fetus continues to grow, it occupies more and more space in the uterus, the amniotic fluid is relatively small, and there is less space for the fetus to move around, so the fetal activity will be weakened. However, if there is a sudden frequent fetal movement, it means that the fetus has already shown signs of hypoxia in the uterus, which is not normal and needs timely examination and treatment. If there is frequent fetal movement, pregnant women can go to the hospital in time to do ultrasound and fetal heart monitoring to assess the condition of the fetus and placenta, to clarify the cause of frequent fetal movement, according to the doctor’s recommendations for targeted treatment.
