No period crisis 😱

Hey everyone I need a little help. So i’m on birth control but this pack I started a week after my period and I wasn’t taking them at the exact time every day. FAST FORWARD so I had sex on pill day 9 however the condom broke and he did ejaculate. So the next day I took a plan b to be safe. But my period was supposed to come 3 days ago and I still haven’t gotten it. Do you guys think the big dose of hormones and my birth control could cause me to skip this period or could I be pregnant?
