An ectopic pregnancy occurs when the fertilized egg implants in
tissue outside of the uterus, and the placenta and fetus begin to
develop there. The most common site is within a fallopian tube;
however, ectopic pregnancies can occur in the ovary, the abdomen,
and the lower portion of the uterus (the cervix).
