An ectopic pregnancy is a complication in pregnancy where the embryo attaches itself outside the uterine cavity. These pregnancies rarely result in a viable fetus and are highly dangerous and life-threatening to the mother. The vast majority of ectopic pregnancies involve the Fallopian tube, and these are called tubal pregnancies, however, implantation can also take place in the ovaries, cervix, and abdomen.
