	A [[Chorionic Hematoma]], also known as a subchorionic hemorrhage or bleed, is a form of bleeding that occurs between the chorionic membrane surrounding the embryo, and the uterine wall. It is the most common sonographic abnormality detected in the first trimester of pregnancy and can lead to complications such as miscarriage and premature labor.

A [[Chorionic Hematoma]], also known as a subchorionic hemorrhage or bleed, is a form of bleeding that occurs between the chorionic membrane surrounding the embryo, and the uterine wall. It is the most common sonographic abnormality detected in the first trimester of pregnancy and can lead to complications such as miscarriage and premature labor.
