ive been on 2 different ills, and im currently on depo provera. I was originally put on the pill when i was 13 due to really really bad periods, after trying 2 different kinds, the pain was still really bad, so the doctor suggested the jab. I've been on it now for 2/3 years. A lot of people dont like it cause it stops periods (not always, but usually), you can put weight on (i did, but i lost it all), and another thing, the only thing that bothers me, i get very light bleeding about 3 days per week.
