I lost my packet of birth control pills

I lost my packet of birth control pills, and i didnt get a new pack. I was at the beginning of my third week. After i stopped taking them, i got my period the next week, when i was supposed to be on my third line of the pill. After my period was over, i had sex and we did use a condom, but i was wondering if since i was screwed up on my pill pack, if that would effect how long it would take for me to get my period again, and what are the chances that i could be pregnant?
