I had my first shot in December and everything was alright until New Years when I got my period. I've been spotting since New Years and it won't stop at all. I'm horribly moody and am having such horrible cramps walking is even painful. When I talked to the doctor she said that would all go away when I get my next shot. I don't want to get the shot again because I'm worried about having my period never stop. My boyfriend has been reading up on the shot and is worried about the long term affects of the shot. Does anyone know if this is normal for the shot? Also the spotting is heavy enough for me to have to constantly wear a tampon. This shot is messing with my body bad I think.
