Most pregnant women may have no obvious symptoms when the fetus just has no fetal heartbeat, which is the main reason why many pregnant women do not seek medical attention in time. However, there are a few pregnant women who will have some symptoms after the fetal heart stops, such as pregnancy reaction disappears, abdominal pain and irregular vaginal bleeding, etc.: 1. pregnancy reaction disappears: after the fetal heart stops beating, pregnancy reaction may also disappear, and pregnancy vomiting or drowsiness symptoms may suddenly disappear, which should be considered as a result of the fetal heart stopping; 2. abdominal pain: after the fetal heart stops beating, pregnant women may have small stomach If a woman stops menstruating after pregnancy, but irregular vaginal bleeding suddenly occurs during pregnancy, with less bleeding than menstruation and dark red bloody leucorrhea, it may be a stillborn fetus discharged after fetal heartbeat stops; 4.Fetal movement decreases or even disappears: fetal heartbeat disappears Usually appear after the fetal movement disappears, so if the fetal movement suddenly decreases or disappears in the middle and late pregnancy, it is highly suspected that acute fetal hypoxia has occurred, resulting in fetal death in the uterus and the disappearance of fetal heart, so it is very important to monitor fetal movement in the middle and late pregnancy.
