Fetal arrest can occur without bleeding or abdominal pain, and cannot be judged on the basis of whether or not there is bleeding and abdominal pain, but in fact most pregnant women experience vaginal bleeding and abdominal pain after fetal arrest. Fetal arrest usually occurs in early pregnancy. When the embryo dies in the uterus, the hormone levels in the pregnant woman’s body will drop, and slowly the blood vessels between the mother’s body and the embryonic tissues will dissociate, leading to vaginal bleeding in the pregnant woman to facilitate the expulsion of the arrested embryo from the body temperature. At the same time, abdominal pain may occur during the expulsion of the embryo. In the early stage of fetal arrest, the pregnant woman may not have bleeding, abdominal pain, or uterine contractions, but at this time ultrasound can detect fetal arrest. It is recommended to pay attention to rest, avoid strenuous exercise and prohibit coitus in the early stage of pregnancy. Surgery should be done as early as possible after the occurrence of fetal arrest. Don’t be lucky just because there is no bleeding, as the dead embryo staying in the uterus for a long period of time may cause intrauterine infections, disseminated intravascular coagulation and other problems.
