Under normal circumstances, the number of fetal movements is not less than 3-5 times in one hour, and the number of fetal movements in 12 hours is more than 30-40 times. If the fetal movement is frequent and regular at 36 weeks of pregnancy, it may be caused by excessive fetal activity, so there is no need to worry excessively; if the fetal movement suddenly becomes violent and frequent without any regularity, it is recommended to visit the obstetrics department immediately to find out the cause and give timely treatment. At 36 weeks of pregnancy, due to the fetal development, the range of activities in the uterus becomes relatively small, the fetal activity is limited, coupled with the decrease in amniotic fluid, the frequency and intensity of fetal movement will generally decrease, so frequent fetal movement at 36 weeks of pregnancy can promptly seek medical attention for fetal heart monitoring. If the fetal heart monitoring indicates fetal hypoxia, it is considered that the fetal amniotic fluid is too small or the umbilical cord is wrapped around the neck or the placenta is declining, etc. It should be combined with ultrasound examination to confirm the fetal safety, and the pregnancy may need to be terminated in emergency.
