birth control
"I've been on this medicine for about 3 years. I haven't expirenced anything unusual...I initially started taking it for irregular periods (I'd only get 11 days between each, which sucked) and to maybe clear up my acne. It definitely got me regular, although didn't help much with acne, it didn't make it worse or change the current condition.  It has worked 100% of the time for me, even with not being perfect while taking it.  It's a great contraceptive if you're good at remembering to take it everyday...(Which I'm not sometimes) so I'm currently in the transition of trying out the nuvaring, it has one different hormonal ingredient then sprintec, but I'm not too concerned the side effects will be any different (if any at all)."
