Okay I am 16 and my mother put me on the Depo Shot I got it twice. My periods have not came the whole time I was on it and didn't after I stopped taking the Depo Shot. After you stop getting it and while you are on it could this shot make your emotions go through the roof? I have been wondering this for a long time and my doctor is not helping me at all. For me I have been taking my emotions out on my bf and I really need some help so I can let him know what is going on. My last shot wore off back in January. Please please help me figure out what is going on and yes I did gain a lot of weight as well due to being put on the shot as well.
