Normal fetal movement is 3-5 times per hour, if the frequency of fetal movement is more than double than usual, it is considered frequent fetal movement. Most pregnant women feel the fetal movement only at 20 weeks, after 28 weeks should officially count fetal movement, generally frequent fetal movement is the fetal intrauterine hypoxia indicators. The method of counting fetal movement is to count one hour each in the morning, midday and evening, generally about 3-5 fetal movements in one hour, and more than 30 fetal movements in 12 hours. If the frequency of fetal movement suddenly increases, more than 1 times faster than the usual frequency of fetal movement, followed by a sudden slowdown of fetal movement, it indicates abnormal fetal condition. Generally, when the fetus is hypoxic in the uterus, the first manifestation is frequent fetal movement, and after struggling weakness, the fetal movement will be reduced accordingly, which is manifested as reduced fetal movement. And the number of obvious fetal movement for 12 hours is more than 30-40, if the fetal movement is regular, rhythmic and not much change, it proves that the fetal development is normal. If the fetal movement is frequent in the second trimester, you should pay attention to bed rest and avoid strenuous exercise. If it is relieved after rest, no special treatment is needed. If the frequent fetal movement is not relieved after rest, you should consult a doctor in time.
