Ectopic gestation refers to a pregnancy that occurs outside the uterus. This condition can be life-threatening and requires immediate medical attention. Synonyms for ectopic gestation include tubal pregnancy, extrauterine pregnancy, and implantation outside the uterus. Other terms that may be used include tubal abortion, cornual pregnancy, and cervical pregnancy. While ectopic gestation is relatively rare, it can occur in women who have had previous pelvic surgery, a history of sexually transmitted infections, or are using assisted reproductive technologies. Symptoms of ectopic gestation include sharp abdominal pain, vaginal bleeding, and dizziness. It is important to seek medical attention immediately if these symptoms occur during pregnancy.
