birth control
"I started taking the Depo shot when I was 17, however it did help effectively with me not getting pregnant, and I did not have any periods for four years, but it caused me to have crazy mood swings, insane depression, and made me feel down all the time. I switched to the birth control pill now that I'm 20 and I don't feel like I'm going completely crazy now! So I do not recommend this birth control at ALL!"
