I started my first Depo shot about 7 weeks and 3-5 days ago, I am 19 and going on 20 here in 3 months. I started to have spotting a few days after my first shot which I was told was normal, then now I feel I am bleeding I think it's lightly or medium, but it's bright red, is it normal or what? I am bleeding a little more than spotting, I also keep feeling like I'm about to start my period but I don't.
