Subchorionic Hemorrhage

Topic Contents

Topic Overview

A subchorionic hemorrhage is bleeding under one of the membranes (chorion) that surrounds the embryo. It is a common cause of bleeding in early pregnancy. It also may be called a subchorionic hematoma.

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.

Call your doctor today if you have any bleeding during your pregnancy.
