Pregnancy scare

Hi! I’ll jump right into it. I had sex over a week ago. I’m on birth control but the condom broke. I’m scared I’m still pregnant since I’m feeling off. Sincere I’m going on holiday in a week, I was wondering if I could stop the strip of pills (21) a few days earlier to get my period sooner. Is this possible? Because I heard you could still bleed and that that is not your period. I’m stressed out and I really want to know as soon as possible. Could someone help me with this?
