Ectopic (tubal) pregnancy occurs when the fertilized egg implants outside the uterus, usually in one of the Fallopian tubes (oviducts).

Ectopic pregnancies are not uncommon and can be life threatening if a diagnosis is not made early. Ectopic pregnancies can be found most commonly in one of the fallopian tubes but can also be found on the ovary, the cervix, in the abdominal cavity, and at the junction where the fallopian tube and uterine cavity meet (called the uterine cornua).
