"i started taking sprintec at 15, and have been taking it for a little over a year now, because my dermatologist recommended it, and said it would help regulate my period and stop cramps. and it did just that! i have not had sex yet, so i have no personal experience for pregnancy prevention, however i hear it works very well. i had no side effects except a little weight gain in my breasts - i went from a 34 b to a 36 c. but every birth control has different effects on different girls. don&#039;t be afraid to give this one a try."
