What are my chances?

I thought I was meant to be ovulating next week but I took my OPK this morning and got my first flashing “high fertility” face. From past experience this most likely means I’ll ovulate on either Saturday or Sunday.

My husband is away until Saturday night and the last time we had sex was on Tuesday (see picture below).

What are my chances of pregnancy if we only had sex Tuesday and try again on Saturday or Sunday?
