Pregnancy begins with a fertilized egg. Normally, the fertilized egg attaches itself to the lining of the uterus. With an ectopic pregnancy, the fertilized egg implants somewhere outside the uterus.
An ectopic pregnancy typically occurs in one of the tubes that carry eggs from the ovaries to the uterus (fallopian tubes). This type of ectopic pregnancy is known as a tubal pregnancy. In some cases, however, an ectopic pregnancy occurs in the abdominal cavity, ovary or neck of the uterus (cervix).
An ectopic pregnancy can't proceed normally. The fertilized egg can't survive, and the growing tissue might destroy various maternal structures. Left untreated, life-threatening blood loss is possible. Early treatment of an ectopic pregnancy can help preserve the chance for future healthy pregnancies.
