hi my name is Jessica. I have been on birth control since 13 and in april I got off of the depo shot and haven't taken anything up until now. my fiancé and I want to have a baby so we went to my OB and he put me on provera. im on my 8th day and I started spotting on the 5th day. my dr said id either most likely start between the 7th or the 10th day. im trying to be patient but I have everything that goes with my periods I had before. severe crippling cramps, migranes, fatigue, neaseua, backpain, decreased eating, weird cravings, and achy body. What is going on?
