I had a miscarriage on September 18, 2010. Going by my last missed period I should've been around 8-9 weeks pregnant. The ultrasound indicated that I was only about 4-5 weeks along so they started monitoring my hormone levels. In the 3 separate days of tests the doctors noticed that my levels were not increasing as they should and informed me that I would more than likely miscarry. The bleeding started two hours after the phone call. About 4 weeks later I returned to my doctor to make sure everything was going ok, as ok as these things can... But all she did was the "finger" exam, gave me a prescription for Depo and sent me on my way. About 2 weeks after getting my depo shot I took a random pregnancy test, don't ask why, and got a bold line and a faint line. It was faint, not like you had to squint and wonder if your mind was playing tricks on you, but not bold like the other. I chalked this one up to the hormones still being in my body after the miscarriage. Now however, almost 4 months later I take another pregnancy test and get the same exact result. So my question is, is it possible for the Hcg to stay in your body this long, and I should be worried because I didn't have a complete miscarriage, or is it possible that even after being on BC (with no antibiotic interference) that I am pregnant again? I am really worried here. Another kicker I have not had a period since June after being regular my whole life... Please Help!
