Clinical Information

Information for Patients


Ectopic Pregnancy

Also called: Abdominal pregnancy, Tubal pregnancy

The uterus, or womb, is the place where a baby grows when a woman is pregnant. If you have an ectopic pregnancy, the fertilized egg grows in the wrong place, outside the uterus, usually in the fallopian tubes. The result is usually a miscarriage.

Ectopic pregnancy can be a medical emergency if it ruptures. Signs of ectopic pregnancy include

Get medical care right away if you have these signs. Doctors use drugs or surgery to remove the ectopic tissue so it doesn't damage your organs. Many women who have had ectopic pregnancies go on to have healthy pregnancies later.
