A subchorionic haematoma is a collection of blood that forms between the membranes surrounding the gestational sac and the wall of the uterus, and is sometimes seen incidentally on an early pregnancy ultrasound. It can be associated with vaginal spotting or bleeding, though many are found without any symptoms at all. Most small subchorionic haematomas resolve on their own as the pregnancy progresses and do not affect the outcome, but larger ones or those with ongoing bleeding may need closer monitoring. Your clinic may advise rest or a repeat scan; contact your clinic promptly, or attend the nearest hospital emergency department if bleeding is heavy or you have significant pain.
