I had my first shot in September. I had unproctected sex with my boyfriend during the first week after the shot. Lately I been extremely tired. I hardly have an appetite, I feel nausea throughout the day, I constantly get headaches, and it seems like I'm losing weight. I already have a 3 year old and these symptoms are very much in common to my first pregnacy. I even look pregnant, don't know if its bloating or is it what I don't want it to be right now!Is it possible to get pregnant on the depo provera?
