So recently I've noticed my body is acting very different. Recently I've been hungry a lot more than normal, I also noticed that I've been getting acne on my back which has never happened to me up until this last couple of weeks. I also have been extremely moody, which only tends to happen while I'm on my period. I'm sexually active with my boyfriend and am on the pill. I don't know if this is just my body acting weird or not. Any suggestions?
