I Made A Typo

So, I was going over my Common App essay last night when I made an unfortunate discovery: I was missing a period at the end of two of my paragraphs. I am FREAKING out!! I applied to Yale early action so obviously I can’t fix the errors. What should I do? I proof read my application three times before I sent it in and my dad read it over twice. Maybe they won’t notice? Or care? I don’t know what to do!
