Miscarriage does not always result in bleeding. Although the vast majority of miscarriages result in vaginal bleeding, some people do not experience vaginal bleeding in the case of indolent miscarriages, also known as abortions, and this varies from person to person. The duration and amount of bleeding varies depending on the cause of the miscarriage. When a pregnant woman has a miscarriage, the uterine lining is shed and expelled through uterine contractions. Therefore, most women experience vaginal bleeding after a miscarriage, which is not heavy and usually stops spontaneously after 3-5 days, up to 1 week. Patients may experience vaginal bleeding along with abdominal pain and reduced pregnancy response. In case of indolent miscarriage, a small number of patients may have no manifestations, neither abdominal pain nor vaginal bleeding, but early pregnancy reactions such as nausea and vomiting may gradually decrease or even disappear, and the embryo is found to have stopped when they go to the hospital for routine obstetrical examination, which indicates the occurrence of indolent miscarriage.
