Still have a chance?

Hi this is my 5th month tracking ovulation and trying for a baby and I just got a positive opk but my husbands out of town, we last had sex Sunday night and I know sperm can live for 5 days but I’ve seen conflicting data of what chance you have of getting pregnant by the days leading up to ovulation and was wondering if anyone had a clear answer? I just wanna prepare myself if my chances are lower than they’ve been the last few months I was able to have sex on ovulation day
