Ok I'm 17 and haven`t had a period for three cycles so I went to my doctor and she put me on medroxyprogesterone 10mg. And said my period would start the following week after I finish the pills and I did I bled A lot. But 3 months before while I was missing I went to a party and well.. got drunk and feel asleep on the chair and I don`t know if any thing happened. And well I just can't seem to shake the fact of thinking I'm pregnant... I'm really scared and I don't know what to do. When I did bleed there wasn`t any pain just a lot of blood. I'm now currently on birth control and still have a week and a half till my scheduled period should come.. but I just can't shake this feeling that I'm pregnant..
So what I want to know is.. is it possible to have a major bleed on medroxyprogesterone and still be pregnant?
