birth control
"I was on depo for 5 and a half years (16-21), it worked wonders for me. I had awful periods before the shot. After the first shot, I had a light period for about 3 weeks but no period or spotting ever after that. I did not gain weight, I actually lost weight. It does make you hungry ALL the time for the first few months but I was wise about my snack choices with I believe helped alot. This was the only form of B.C. me and my boyfriend used for the entire time and no babies. It does take some getting used to not having a period to confirm you aren't pregnant at first. When we decided to have a baby, it took 8 months to get pregnant. I didn't have any serious issues and loved it."
