Ectopic Or New Pregnancy??

Stephanie • None of your business.
So, I've posted this before, but four weeks ago I had laparoscopy for my second ectopic pregnancy. I kept both of my tubes. Monday night I went to the E.R. (Three and a half weeks after surgery) and my HCG levels were 738. I was only intimate with my fiancé May 4 and May 8. My question is, is it possible to have already gotten pregnant again or is this leftover tissue in me? I'm going to the doctor Monday but I still wonder.. After surgery, my pregnancy symptoms went a way for about two weeks and now they're all back. My boobs hurt so bad, I'm constipated, hungry all of the time, and sleepy/weird dreams. All of the typical things that happen to me during pregnancy. Has anyone been in this situation before or a similar one? What was your outcome?
