Fetal movement is caused by the activity of the fetus in the uterine cavity impacting on the uterine wall, the fetus will appear in the uterus stretching, kicking movements. Due to the early stages of pregnancy, the fetus is weak and the initial fetal movement is relatively insignificant and most pregnant women are unable to perceive it, which may appear similar to the peristalsis of the gastrointestinal tract tubes. Most pregnant women can obviously feel the fetal movement at 16 to 20 weeks of pregnancy. Normal fetal movement indicates that the placenta is functioning well, sufficient oxygen is being delivered to the fetus, and the fetus is growing and developing soundly in the uterus. However, if a pregnant woman is not aware of fetal movement at around 20 weeks, she should pay attention to the fact that it may be caused by fetal hypoxia and should go to a regular hospital for relevant examinations. Pregnant women need to undergo regular checkups during pregnancy to understand the growth and development of the fetus.
