Lost pill

Lauren
So I went to take my birth control tonight. Well... I dropped the pill into the garbage can... So I took Sunday's pill instead. It's my last week of pills before my period week. But obviously the end of this week, Saturday, I'll be short one pill. So should I just skip that day taking one at all? Or start period week then? I've literally been perfect taking my pill, over a year, till this point so it's freaking me out. We plan to use condoms in case, just till my next pack, but still need piece of mind. Advice? Thanks ladies.
