Normally, the child should produce a germ and a fetal heart at about 60 days of pregnancy. If there is no fetal heartbeat in a 3-month-old child, this is a situation where the fetus has stopped developing and should be aborted in time. During this period, an ultrasound should be done to see the size of the gestational sac. A 3-month-old fetus is fully developed and the fetal heartbeat that occurs only after it is fully developed and formed needs to be induced, and the fetus should not be kept in the uterus for too long. If the fetus has died and stays in the uterine cavity for too long, it can easily lead to inflammatory infection in the uterine cavity, and in serious cases, it can also affect the health of the pregnant woman, who needs to be induced in time for treatment, and can take oral induction drugs such as mifepristone and misoprostol.
