Placebo week?

I ended my placebo week on Sunday, and started my active pills yesterday (Monday) at 1:00 but I had sex last night with my boyfriend. We used a condom like we always do since we always want extra protection but if for whatever chance (don’t think this happened but) the condom broke or something could I be at risk for pregnancy? I’ve been on the pill (combination pill) for almost a year now. Thanks!
