Ectopic pregnancy occurs when the egg implants outside of the uterus, most times in the Fallopian tube. This is a rare occurring in only 2% of the American population. There are different causes for ectopic pregnancy including infertility, previous ectopic pregnancy, and the most common cause PID from an untreated chlamydia infection (another reason to get your annual check ups! Most chlamydia infections show no symptoms and can have consequences as serious as infertility). If an ectopic pregnancy occurs it can be managed with medicine or surgery. Pregnancy is possible after both. If the tube ruptures this is emergent and must be treated immediately. Your first ultrasound after a positive pregnancy test will determine that the egg has implanted in the correct place. Info on ectopic pregnancy can be found on American College of Obstetricians & Gynecologists website.
