Birth control while breastfeeding

In need of advice, any mommies out there that are breastfeeding or at some point breastfed their babies can u please help me out I had my baby girl two months ago she is EBF and we were doing good until last night I took my birth control pill last night for the first time "the mini pill" and my baby who usually sleeps 4-5 hrs at night woke up every 2-3 hrs and breastfed for longer periods and after she finished she would suck her hands like she still hungry, is my milk supply being affected by the pill?? Should I stop?
