Subchorionic Hematoma: Care Instructions

Your Care Instructions

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.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

How can you care for yourself at home?

  • Keep track of any bleeding, and follow the guidelines for when to call your doctor.
  • Keep in mind that some bleeding during the first trimester or an abnormal finding on an ultrasound may:
    • Not cause any problems for you or the baby.
    • Turn out to be something more serious. But if this happens, it's best to find out early. Then you and your doctor can manage any complications sooner rather than later.

When should you call for help?

Call 911 anytime you think you may need emergency care. For example, call if:

  • You have sudden, severe pain in your belly or pelvis.
  • You passed out (lost consciousness).
  • You have severe vaginal bleeding.

Call your doctor now or seek immediate medical care if:

  • You are dizzy or light-headed, or you feel like you may faint.
  • You have new or increased pain in your belly or pelvis.
  • You have new or more vaginal bleeding.
  • You have pain in the vaginal area.
  • You have a fever.
  • You think you may have passed tissue. Save any tissue that you pass. Take it to your doctor's office as soon as you can.

Watch closely for changes in your health, and be sure to contact your doctor if:

  • You have new or worse vaginal symptoms, such as pain, itching, or a discharge.
  • You do not get better as expected.
