It is not normal to feel no fetal movement for a day in 29 weeks of pregnancy. Under normal circumstances, fetal movement should be greater than or equal to 10 times/2 hours, and abnormal fetal movement requires prompt medical attention. Self-monitoring of fetal movement by the pregnant woman can assess the condition of the fetus in the uterus. Fetal movement occurs around 20 weeks and may occur earlier in PMS women. Fetal movement usually disappears briefly for about 20-40 minutes during fetal sleep. If fetal movement decreases or disappears for a long period of time, it is necessary to be alert to the occurrence of intrauterine hypoxia. If there is a decrease or disappearance of fetal movement, it is necessary to consult the doctor in time, improve the fetal heart, ultrasound and other examinations to assess the existence of fetal hypoxia, if it is considered to have intrauterine distress, it is necessary to follow the doctor’s instructions for treatment.
