Fetal movement usually occurs at 12 weeks of gestation, but more often than not at 16 weeks of gestation, pregnant women can consciously move their fetuses. Fetal movement refers to the fetal body activities, generally at the end of the 12th week of pregnancy when the fetal limbs can move, but because the fetus at this time is small, and the amplitude of the activity is not large, generally can not be felt. Most pregnant women will be able to consciously feel the fetal movement at 16 weeks of pregnancy, and with the growth of the fetus and gradually enhanced. Fetal movement is usually more active at night and in the afternoon. After 28 weeks of gestation, fetal movement counts should be performed as prescribed by the doctor to self-evaluate the condition of the fetus in the uterus. Normal fetal movement counts are ≥10 movements in 2 hours, excluding the 20-40 minute fetal sleep cycle. However, a fetal movement count of <10 movements/2 hours or a 50% decrease in overall fetal movements may indicate the possibility of fetal hypoxia and require prompt medical attention. Fetal movement count is a simple and economical method to evaluate the intrauterine safety of the fetus, and when fetal movement is reduced or frequent, it is necessary to go to the hospital in a timely manner.
