"i have been taking sprintec for a little over 2 years and have had no severe side effects. my periods were very irregular and could last up to a month before i started taking sprintec. now i get my period every month down to the day i am supposed to start and last 3-4 days. my breasts have gotten larger and i have a few mood swings, mostly around the time of my period. i would recommend taking sprintec."
