What Are The Side Effects Of Sprintec?

Hi, i am 20 yrs old. 3 weeks from now i will be married. Recently i got on Sprintec and i do not believe that it is a low hormone dose. But this past 2 1/2 months have been awful. I have no sex drive anymore! Totally lost it. How can i change this? I figure i should switch birth controls but im not sure which one would be better for me.
