Confused girl

Yasmina

I've always had irregular period due to PCOS and so my gyno gave me Diane-35 to fix the cycle . I finished the pills in the pack (21 days and then I stop for 7 and continue like that) so I'm off it and I'm in my period. I've gotten blood clots and Ive never gotten them before so I'm confused and worried. Should I be worried?
