An ectopic pregnancy is a when an embryo sticks to somewhere outside the uterus. In a normal pregnancy, the embryo sticks itself into the wall of the uterus. The uterus is the only place in the body where an embryo can grow into a fetus.
Most ectopic pregnancies happen in a Fallopian tube (one of the two tubes that connect the ovaries and the uterus). For this reason, ectopic pregnancies are often called tubal pregnancies. Rarely, ectopic pregnancies can happen in an ovary or in the cervix.[1]
Ectopic pregnancies cannot become normal pregnancies, and will not result in a baby. They can also cause serious health problems for the mother.
