I had a medical abortion at 7 weeks pregnant. I took the Misoprostol about 4 weeks ago on October 1st. I had unprotected sex 2 weeks ago. I went in to see my doctor yesterday for birth control. They gave me the depo shot and also drew my blood to check my HCG levels. This morning I woke up to a voicemail from my doctor’s office that said my HCG levels came back positive, but low at a 37 and that I need to come back in two weeks to check them again. Am I pregnant again? What are the chances of this being a false positive?
