birth control
"I'm 24 & been on depo for 7 straight years. I got on it young so it wasn't to be used as a contraceptive but to help my very heavy periods. I bleed heavily  7 days straight, ridiculous cramps and migraines. I actually spotted for 3 months straight when I started it!! I was ready to call it quits when all of a sudden my periods stopped completely after! I was elated. No more cramps! I started to spot around the time for my next shot,  for a few years but as of now I never bleed. I may get light cramps for a day. I never experienced any weight gain or craziness from it. However, I do now suffer from depression and constant irritability... But my life and work is very stressful so I don't feel like it's the depo but it could be worsening it."
