Ok so here's the deal.. I had unprotected sex about three weeks ago, then I took the morning after pill 48-72 hrs later. My period was a week late so I took two tests. Both were positive. The next day I started bleeding and I went to the clinic. They also did two tests, one positive, one negative. The next day the bleedng stopped. They said they didn't know for sure what was going on, that I needed to take another test a week later... the bleeding started again today. Kind of like a normal period but black or brown not red. Semi light, on and off... WHAT IS GOING ON?

False positives are very rare. You had 3 positives, so I'd say you're pregnant. The bleeding is a concern, and should be discussed with your OBGYN.
