had sex five days prior to my ovulation Could I Be Pregnant?

I had sex five days prior to my ovulation date which is supposed to tomorrow, but I think it's happening right now. (i'm pretty in tune with my ovulation, it hurts quite a bit.) But it was unprotected sex and although he didn't fully cum in me, he didn't pull out in time. Is there a high chance of pregnancy because of the time I had sex at? I'm quite young still and am not trying to conceive at all, but if it happens i've talked to my boyfriend and we know the plan we'll go through with.
I really want to know so if people could answer that would be amazing.
