Time zone change? Bc pills? HELP!

An
So I just started bc pills a few days ago and I take them at 8.15am. I live on the east coast and I'm going out of town soon to Chicago which is an hour behind. Will I need to take my pills at 7.15am instead while I'm there?? It's just a short 3 day trip.. but I don't want to screw up my protection!
