"i have been on sprintec for a year now. it is good in that it&#039;s only $9, it has prevented pregnancy, and periods are only a few days. every time i start a new pack (after period) i get severely nauseated for several days, so i am finally going to go back to the doctor and try something different. during certain times i have very swollen and tender breasts, but that&#039;s not too awful to bear."
