I have been told that the depo shot hurts but only if you get it in your arm. People have said that they get it in their butt and it doesn't hurt as bad. And my main concern is the bleeding... since I have a heavy period (lasts 8 days) and I have to wear a pad and the super plus tampons, will the bleeding be worse or better with the shot? I am terrified of needles but I really am looking into getting this shot.
