Self-perceived fetal movement usually starts around 4-5 months of age, and most pregnant women will have significant self-perceived fetal movement at around 18-20 weeks. There are individual differences, some pregnant women may feel the fetal movement earlier, and some may not feel the obvious fetal movement until after 5 months. The fetal movement is an indication of the good condition of the fetus in the uterine cavity, and pregnant women should pay attention to the fetal movement every day after it appears. It is recommended to start counting fetal movements after 7 months of pregnancy, 3 times a day, 1 time in the morning, 1 time in the afternoon and 1 time in the evening, 1 hour fetal movement is about 2-3 times, 12 hours fetal movement is about 30 times. If there is too much fetal movement or too little fetal movement, you must go to the hospital in time to check and listen to the fetal heart.
