It is normal for simple fetal movement to increase in late pregnancy, but when fetal movement is frequent or gradually decreases or even disappears after an increase in fetal movement, it is necessary to go to the hospital in time. Generally, pregnant women can consciously move the fetus around 20 weeks of gestation, and after 28 weeks of gestation, fetal movement is ≥10 times/2 hours, with the increase of gestational weeks, fetal movement also increases. A simple increase in fetal movement in late pregnancy is generally normal, but frequent fetal movement may be abnormal. If fetal movement increases and then decreases and disappears, it is not normal, and there may be fetal hypoxia, timely hospitalization. Fetal movement counting in late pregnancy is a simple and economical way to self-evaluate the well-being of the fetus in the womb. Fetal movements are usually more active at night and in the afternoon. It disappears during the sleep cycle, which usually lasts for 20-40 minutes. When fetal movement is less than 10 times/2 hours or 50% less, or when there is frequent fetal movement, it is necessary to go to the hospital for consultation.
