Anybody take Sprintec?

Andria
I have been bleeding for almost three weeks. Not heavy tho. Last night I started getting horrible menstrual cramps that radiates down to my knees and then got a severe migraine that I woke up continuing to have. Has anyone else felt like this? I'm kinda scared to keep taking it..my doctor has me skipping the placebo pills for first two months also because I wanted the birth control to where you only bleed once every three months but my insurance doesn't cover it sooo
