Pregnant women lie on their left side and count the fetal movements for one hour in the morning, one hour in the middle of the day and one hour in the evening, and multiply the number of movements by 4 to get the number of movements in 12 hours. After 28 weeks of pregnancy, fetal movements gradually become regular, and counting fetal movements is the simplest and most direct way to monitor the condition of the fetus in the uterus. We usually use the number of movements in 12 hours to assess the condition of the fetus. If the number of movements is greater than or equal to 30, with no less than 3 to 5 movements per hour, it is considered normal, indicating that the placenta is functioning well, which is a sign that the fetus is healthy and strong. If the number of fetal movements in 12 hours is less than 30 or 50% less than the original number, it is possible that the fetus is in intrauterine distress. It is recommended to consult the obstetrician for fetal heart rate monitoring and ultrasound to rule out the possibility of umbilical cord around the neck, or low amniotic fluid or intrauterine oxygen deprivation. It should be noted that fetal movement varies from person to person, which is also very much related to the character of the fetus and the condition of the mother. Some fetuses move a little more frequently, but as long as they are regular, rhythmic and do not change much, there is no need to worry too much and no generalizations should be made. During pregnancy, mothers should pay attention to rest, maintain balanced nutrition, be in a good mood, and have regular checkups to prevent fetal abnormalities. If there is any discomfort, consult a doctor in time and do not take any medication on your own.
