I was just wondering if I could be pregnant. I got the depo shot on November 15th of 2014... And my doctor said that it only lasts for three motnhs, and I think I might be pregnant... I started spotting about three weeks ago and it lasted for two weeks. (I stopped spotting a week ago) but when the spotting stopped I started getting food cravings, and my boobs have been hurting. I also feel bloated. me and boyfriend dont use contraception because of the birth control I was on, but now I don't know what to do, because I could be pregnant or my period could just be late... I dont know.
