I have been on the shot September 17th of this year (2010), I have been bleeding for 2 weeks going on 3.. The bleeding hasn't stopped, some days it is light for a short period of time then goes back to being regualr i guess you could say. This week I have been bloated, I pee more frequently, I eat more than usual, I get head aches easily, I am always tired. I am wondering if these are normal side effects from the Depo Provera, or is it possible I am pregnant?? Before I got on the shot I thought I was pregnant, so me and my boy friend didn't use protection, at the doctors they took a pee test I am wondering how many days it would of told me if i was pregnant.. We had sex with out using any other methods of birth control. Please help with best answers as possible

Thanks
