How long it takes to show signs after fetal termination depends on the individual. Some people may not have any symptoms, some may have a reaction before the abruption or may have a reaction within a few days or 1-2 weeks. 1. Asymptomatic: Some pregnant women may not experience any symptoms after the abruption, and may only discover the abruption during regular checkups. 2. Symptomatic: some pregnant women may already have a small amount of vaginal bleeding before the abruption, and then the abruption will be found after medical examination; if the pregnant woman’s own pregnancy reaction is more obvious, usually a few days after the abruption, the pregnancy reaction will be weakened or even disappear; and some pregnant women may have vaginal bleeding, lower abdominal cramps, and other symptoms in the 1-2 weeks after the abruption. It can be seen that if a pregnant woman experiences a small amount of vaginal bleeding, pain in the lower abdomen or a sudden weakening or disappearance of the pregnancy reaction, she should consult a doctor promptly to check the development of the embryo.
