Stupid question but please help

So, 4 days before my fertile window my boyfriend and I had unprotected anal and he also fingered me. He didn't finish at all in me and we were on our sides during the intercourse. He said his hands were dried and he cleaned himself off from anything that couldve been on him.. I was wondering if I could've gotten pregnant from that? I've always had bad anxiety and o just wanted to make sure that I'm just over reacting
