birth control
"When I started getting the depo shot I was 15. It was a lot easier to do that than have a 15 year old remember to take a pill everyday. The only downsides to this shot were the constant hunger and the going back to the doctor every 3 months to get another one. I did experience weight gain, but I mean c'mon, if you're going to eat more, then you have to exercise more. I took it for 3 years and had not gotten pregnant. Just use common sense and you will absolutely love the shot!"
