I MC dec 5th. (Medicine induced) I have been taking pregnancy tests to see when my levels reached Zero. I NEVER  got a negative test or my AF. So the dr. Told me to come in. She said I could be pregnant!?!? She is checking my blood to see if it doubles. Has this happened to anyone? I'm very nevrvous. I have been spotting brown for the whole month and I'm scared that if I am pregnant I'll MC again! Please help!
