Contraceptive Pill?

Daphne
Hi, I'm 13 & i was put on the contraceptive pill 'Diane' by my docter on Friday, it was for my skin & irregular periods. I've taken it twice now at the same time, seperate days ofc. I finished my period two days ago and i just wiped in the bathroom & i have blood again... is this a normal sympton? Have i just started my period again or what?
