I started birth control a week before my period’s due, what should I do now?

Patient: I’m 17 and I just started birth control for my first time today. the bad thing is, I didn’t read that I shouldn’t start taking the pill until the day of my period. My period’s not due for another week. Should I just stop and wait until the first day of menstruation to take another pill? I heard it can really mess up your cycle.
