An ectopic pregnancy is a complication of pregnancy in which the pregnancy implants outside the uterine cavity or the womb. With rare exceptions, ectopic pregnancies are not viable. Furthermore, they are dangerous for the mother, internal bleeding being a common complication. Most ectopic pregnancies occur in the Fallopian tube (so-called tubal pregnancies), but implantation can also occur in the cervix, ovaries, and abdominal area. An ectopic pregnancy is a potential medical emergency, and, if not treated properly, can lead to death.
