Can I change my Invisalign trays 2 days early when I'm supposed to be changing them every 10 days?

I'm on tray 1 of my Invisalign treatment that's suppose to change every 10 days. I accidentally left my retainers at a restaurant and I am on day 8.5. I put in my second set of retainers because I didn't think 2 days or so would make a difference. The top fits perfect but the bottom is a little tight. It's Sat night and my dentist isn't open until Mon morning so ordering a new tray would take a few days and I'm afraid for my teeth to move. Should I continue wearing my second set of trays?
