What's the likelihood???

Ok so I gave my bf oral and he said he was about to cum but of course I still proceeded. We ended up having sex after and he pulled out. We've been doing the pull out method for years with no issues. However he said "came" while I gave him oral but I'm sure I would have tasted it. My question is could I get pregnant still? Glow has predicted my fertile week to be 10/15-10/21. I had unprotected sex 10/16. I know it's super early but I was just wondering the likelihood.
