In 2004 I had a ectopic pregnancy which ruptured and I had half of that tube removed. Since then I've had similar pain on that same side. I've been to the ER 4 times since then with these pains and I feel like they think I'm crazy. My last period was 2/11/0 (I'm never late, nothing has changed, on bc), I had a blood pregnancy test come back negative last night when I made my 4th trip to the ER and have an ultrasound scheduled for tomorrow. Please give me advice or if you have had similar problems. I'm just scared, starting to think I'm nuts, and in pain. I know my body and I know this isn't right. The pain keeps me up. They said it wasn't my appendix so, here I am. Thanks!
