It is normal for pregnant women to have fetal movements at 4 months. The vast majority of fetal movements will appear at 16-20 weeks of pregnancy, that is, around 4 months, and after 34 weeks there will be a gradual decrease in fetal movements. Normal fetal movement is not less than 3-5 times in 1 hour, and the number of obvious fetal movements is more than 30-40 times in 12 hours. Some fetuses can move about 100 times in 12 hours. As long as the fetal movement is regular, rhythmic and not much change, it proves that the fetus is developing normally. The period of 28-34 weeks of gestation is the period of active fetal movement, after which it will be slightly weakened until delivery. Pregnant women need to pay attention to the number of fetal movements every day, counting 1 hour in the morning, noon and evening. The surrounding environment should be kept quiet, and it is recommended to count in the left side lying position. 3 hours of fetal movement multiplied by 4 will give 12 hours of fetal movement. If there are less than 20 fetal movements in 12 hours, or more than the normal number of fetal movements in a period of time, frequent fetal movements are called abnormal fetal movements, if abnormal fetal movements occur, you should consult a doctor in time.
