serious emergency!!!'

so my parents are separated and thought I left my birth control at my dads house yesterday and I didn't get a chance to take it. I go there today and it's not there so I think I lost my package. today is the second day not taking it but I'm on my last week, I had yesterday, today, tomo, and Saturday left of regular pills before i started my sugar pill week. what do I do?? just wait until my sugar pills would be over and start a new pack after that? or get a net pack now and start over?? I have no idea!!!!
