Horrible cramps and Sprintec

Hey ladies, so I just started taking the generic form for sprintec this month and when it was time for my period I literally had THE WORST CRAMPS OF MY LIFE! Like horribly sharps pains that left me in bed crying kind of cramps. It got so bad that I just started taking the pill again to stop my period. Has anyone else gotten bad cramps while taking it? I’m trying to get into seeing a dr about it but everything is booked for like a month. And now I’m worried about not having a period every month but there’s no way that I can deal with those cramps and go to work at the same time!
