Ectopic pregnancy occurs when a fertilized egg implants and begins to grow outside the uterus, most commonly in the fallopian tube. Since these areas cannot support a developing pregnancy, the condition is dangerous and requires immediate medical attention. Risk factors include previous ectopic pregnancy, pelvic infections, tubal surgery, and use of assisted reproductive technologies. Symptoms typically appear between 6–8 weeks of pregnancy and may include sharp abdominal pain, vaginal bleeding, shoulder pain, and dizziness or fainting due to internal bleeding. Diagnosis is made through pelvic examination, blood tests for hCG levels, and transvaginal ultrasound. Treatment options depend on the size and location of the ectopic pregnancy and may include medication (methotrexate) to stop cell growth or surgery to remove the pregnancy. In some cases, the affected fallopian tube may also need to be removed. Early diagnosis is critical to prevent rupture and serious complications. With prompt care, most women recover fully and can still conceive in the future.
