birth control
"I was on the ortho Tori cyclin lo all of my high school years. Never had acne, 3 day periods, no cramps, no bloating, and actually believed it was impossible to gain weight on it. Coming to college the price of $110 was too much so I went to the generic. 2 months in I've gained 20 pounds, horrible cramps, and have horrible acne. Switching birth controls after this pack."
