Ectopic pregnancy: A pregnancy that is not in the uterus. The fertilized egg settles and grows in any location other than the inner lining of the uterus. The large majority (95%) of ectopic pregnancies occur in the Fallopian tube. However, they can occur in other locations, such as the ovary, cervix, and abdominal cavity. An ectopic pregnancy occurs in about 1 in 60 pregnancies. Most ectopic pregnancies occur in women 35 to 44 years of age.
Signs and Symptoms. Ectopic pregnancy can be difficult to diagnose because symptoms often are like those of a normal early pregnancy. These can include missed periods, breast tenderness, nausea, vomiting, fatigue, or frequent urination (peeing). Often, the first warning signs of an ectopic pregnancy are pain or vaginal bleeding. There might be pain in the pelvis, abdomen, or even the shoulder or neck (if blood from a ruptured ectopic pregnancy builds up and irritates certain nerves). The pain can range from mild and dull to severe and sharp.
