So on the 7th of march is when i started taking the pill which is when i started my period. I know that the mini pill takes 48 hours to start tk work and stuff. Within 2 weeks of being on it i had unprotected sex and he finished inside me. I have taken it every single day at the exact same time. Well im already on my second pack and i was supposed to atart my period today and i havent started it yet. Should i be worried?
