HELP!! I LOST MY BIRTH CONTROL PILLS!!

So prom was this Saturday and Saturday morning I was driving to my beach house and it was 9:30 (when I take them) and I was at a red light and I took it. I forgot what I did with the pack but I threw it somewhere in the front seat in my car because I was driving. My car is clean. But I can't find them. And this morning I just realized that I didnt have the pack. I'm supposed to start my period tomorrow but since I don't have my pills should I restart a new pack or wait like I'm taking them??
