The bouncing sensation in a pregnant woman’s stomach can be caused by fetal hiccups or normal fetal movements, both of which are normal and usually require no special treatment. Common causes 1, fetal hiccups: fetal movement jumping around, may be the fetus swallowing amniotic fluid too fast and hiccups, this time the pregnant woman will feel the stomach appear paroxysmal, jumping fetal movement; 2, normal fetal movement: in 4-5 months of pregnancy, pregnant women will begin to feel the fetus in the uterus, the feeling is not particularly obvious, as the month increases, the fetal movement gradually obvious. In 28-32 weeks of pregnancy, the fetal movement is the most active, the space in the uterus is relatively large, the amount of amniotic fluid is appropriate, which is conducive to the substantial activities of the fetus, such as turning over, kicking legs, etc., pregnant women may feel a jumping fetal movement. The fetal movement indicates the normal activity of the fetus, and the pregnant woman needs to conduct fetal movement count to observe the fetal activity. The normal fetal movement is 3-5 times per hour, and more than 30 times in 12 hours. Generally, pregnant women count fetal movements in the morning, in the middle and in the evening every day, for 1 hour each time, add up the 3 times and multiply it by 4, which is the fetal movement in 12 hours. If the number of fetal movements increases or decreases significantly, you need to go to the hospital in time to prevent the fetus from intrauterine hypoxia.
