A subchorionic hematoma or hemorrhage is bleeding under one of the membranes (chorion) that surrounds the embryo inside the uterus. It is a common cause of bleeding in early pregnancy.
The main symptom is vaginal bleeding. But some women don't have symptoms. They may find out they have a hematoma during an ultrasound test.
In most cases, the bleeding goes away on its own. Most women go on to have a healthy baby. But in some cases, the bleeding is a sign of a miscarriage or other problem with the pregnancy. Your doctor may want to do a follow-up ultrasound.
