After a miscarriage bleeding can start right away or it may take several weeks to expel the fetus fully. Please see your doctor.
A medical emergency is an injury or illness that is acute and poses an immediate risk to a person's life or long term health. These emergencies may require assistance from another person, who should ideally be suitably qualified to do so, although some of these emergencies can be dealt with by the victim themselves.]citation needed[ Dependent on the severity of the emergency, and the quality of any treatment given, it may require the involvement of multiple levels of care, from first aiders to Emergency Medical Technicians and emergency physicians.
Any response to an emergency medical situation will depend strongly on the situation, the patient involved and availability of resources to help them. It will also vary depending on whether the emergency occurs whilst in hospital under medical care, or outside of medical care (for instance, in the street or alone at home). Abortion
Obstetrical hemorrhage refers to heavy bleeding during pregnancy, labor, or the puerperium. Bleeding may be vaginal and external, or, less commonly but more dangerously, internal, into the abdominal cavity. Typically bleeding is related to the pregnancy itself, but some forms of bleeding are caused by other events. Obstetrical hemorrhage is a major cause of maternal mortality.
The most common bleeding event is the loss of a pregnancy, a miscarriage, medically also called a spontaneous abortion. Bleeding from an early miscarriage may be similar to that of a heavy menstruation, but later on, a pregnancy loss may be accompanied by excessive or prolonged bleeding. A physician may propose to perform a D&C for treatment. An ectopic pregnancy which implies a pregnancy outside the uterus commonly in the tube may lead to bleeding, internally, that could be fatal if untreated.
