The normal number of fetal movements is 3 to 5 per hour, and after 28 weeks of gestation, the 12-hour count of fetal movements is normally more than 30. At about 20 weeks of gestation, fetal movements gradually increase, reaching a peak at 32 to 34 weeks of gestation, and gradually decrease after 38 weeks of gestation. Fetal movement disappears when the fetus sleeps and lasts for 20 to 40 minutes, and is more active at night and in the afternoon. The normal number of fetal movements is 3 to 5 times/hour, and after 28 weeks of gestation, the 12-hour fetal movement count is normally more than 30 times. The method of counting fetal movement by pregnant women: counting 1 time after continuous fetal movement, counting 1 time after interval movement, and counting 1 time as long as you feel fetal movement. Pregnant women every day in the morning, in the middle and at night to choose a convenient and relatively fixed time to count the fetal movement of 1 hour, 3 times the number of fetal movements and multiplied by 4 that is the number of 12 hours of fetal movement. When the fetal movement decreases, the fetus is at risk of respiratory distress, so pregnant women should go to the hospital in time to find out the cause and standardize the treatment when they feel that the fetal movement is decreasing.
