Pregnant women’s stomachs that twitch may be fetal movements, but they may also be conditions such as uterine contractions. If a pregnant woman’s stomach jerks, most of them are normal. For example, when the baby moves in the womb and waves its arms and legs or hiccups, some mothers will feel their belly jerking. This kind of twitching will usually be relieved naturally after half an hour or an hour or so, or it can disappear in a few minutes. The phenomenon may also occur when the uterus grows and the muscle fibers are pulled or the pregnant woman’s abdominal aorta is pulsating. In addition, when the uterus is contracting, the uterus hardens because of the contractions and is in bursts, and the pregnant woman may feel her stomach pumping. If a pregnant woman has a tummy twitch or notices a significant abnormality in fetal movement, she should pay attention to it and is recommended to go to the obstetrics and gynecology department of the hospital for relevant examinations. If this happens only occasionally, just take care to rest more.
