Help me ! Please

So I am ovulating, but I had sex the day before ovulation (12/27/18). I started ovulating (12/28/18). I know sperm lives for 5 days. And it says my ovulation day is tomorrow. Is there a chance I can still get pregnant ? My period isn’t until 1/16/18. I am freaking out because I don’t want kids right now and I was drunk the night everything happened so it was like heat of moment type of deal.
