Worried question!!

Hello! I started taking my new birth control last month.. I had my period at the end of the month from the Sunday it started till that Saturday I did not take birth control than started again on Sunday. After five days of taking it (I’ve taken it everyday but not at the same time ... before 11:00 though) I had unprotected sex. He didn’t finish inside me but we did do stuff before so I’m nervous that I could be pregnant from the cum before .. what are the possibilities!!!
