So last year I decided to try the depo shot, after 3 shots, I stopped, I had gained all this weight and I felt miserable. Depressed, emotional, it was just horrible. I had irregular periods, the reason for going on the shot, it didn't help at all, and now it seems to be worse. I haven't had a period since March, this is the longest span between periods that I've ever had! Should I be worried about it or is this normal after being on the shot?!
