The fetal movement is not a real fetal movement, it is considered to be caused by fetal hiccups. During pregnancy, the fetus swallows amniotic fluid, and if it swallows it too quickly, it will have regular hiccups, which is a relatively normal physical reaction, and the hiccups are like the heartbeat of a pregnant woman. The fetal movement is not frequent and regular, but the hiccups are regular. Around 7 months of pregnancy, the fetus needs to grow and develop to prepare for the birth of the baby, so it will keep swallowing amniotic fluid to promote the development and maturation of the lungs, so there will be hiccups, and pregnant women can not be nervous. You can relax and rest, and you need to count the fetal movements at any time during the second trimester to avoid hypoxia.
