I went on bc when I was 23, but I wish I had done it sooner! I had horrible cramps and got awfully sick from the time I was in high school throughout college, sometimes so unbearable I would have to stay home from school. BC has really helped with the cramps and my periods are very manageable now. I have been on it for 2 years (Apri Oral) and am switching to Yaz on Sunday.
