The early symptoms of an ectopic pregnancy can be very similar to typical pregnancy symptoms. However, you may experience additional symptoms during an ectopic pregnancy, including: Vaginal bleeding. Pain in your lower abdomen, pelvis and lower back. Dizziness or weakness. If your fallopian tube ruptures, the pain and bleeding could be severe enough to cause additional symptoms. These can include: Fainting. Low blood pressure (hypotension). Shoulder pain. Rectal pressure or bowel problems. When a tube bursts, you may feel sudden, sharp lower abdominal pain. This is a medical emergency. You should contact your healthcare provider or go to the emergency room immediately.
