I am on sprintec bcp for over a year its 2 days before i start my white pills i have not skipped and i take them relatively on time. i have light pink-tan discharge with light cramps. i started working out a lot and i am sexually active w 1 partner?

If "relatively on time" for the active component of Sprintec is within the same hour that the previous active pill was taken, you might ask your gyn provider about another type of oral bcp or switch to a straight progestin type. If the "relatively on time" is a less punctual dose than previously recommended on occasion, breakthrough bleeding ("pink, tan discharge") can occur.
