birth control
"I've used this birth control for 8 years. I was a late bloomer, and didn't have my first period until well into age 16, I'm told because I'm small and athletically inclined. I never had cramps or mood swings - but my periods were extremely irregular and would arrive unexpectedly to ruin my favorite pairs of underwear. My doctor selected this initially due to cost, as I was not sexually active and just wanted regulation. Now at age 24, I'm happy to report it's effectiveness at preventing pregnancy, as well as a complete lack of any side effects. No acne, no weight gain, no mood swings, no spotting, no cup size enhancements (unfortunately) and a nice 4-5 day window that I know exactly when and how much I'm going to bleed."
