The continuous body movement of the fetus in the uterus is counted as one fetal movement, and the pregnant woman can judge the growth and development of the fetus by counting the fetal movement herself after feeling the clear fetal movement. Fetal movement mainly refers to the movement of the fetus in the uterine cavity, hitting the uterine wall of the pregnant woman, and then the fluctuation can be felt on the surface of the abdomen. Pregnant women usually start to feel fetal movement at about 20 weeks of gestation, which gradually strengthens with the progress of pregnancy and reaches a peak at 32-34 weeks, and gradually decreases after 38 weeks of gestation. If the duration of fluctuation is continuous, it is considered as one fetal movement. If it moves after an interval, it is divided into several fetal movements. In general, fetal movements are more active at night and in the afternoon, and often disappear during the fetal sleep cycle. Pregnant women can rest for 1 hour in the morning, midday and evening respectively, and record the number of fetal movements. The number of fetal movements in 3 hours is added up and multiplied by 4 which is the number of fetal movements in 12 hours, more than 30 times is normal. The number of daily fetal movements is basically not much different, the sudden increase or decrease of fetal movements should be taken seriously, the frequent fetal movements are mostly physiological phenomena, mostly seen when pregnant women eat, after activities, at night, fetal education and emotional excitement. The pathological frequent fetal movements are mainly related to certain diseases, such as abnormalities of the fetus and its appendages, the pregnant woman combined with gestational medical and surgical diseases or external impact, etc. It is recommended to go to the hospital immediately to perform ultrasound or fetal heart monitoring examination, and then treat the symptoms to avoid intrauterine hypoxia of the fetus.
