Chances of conceiving this month!?

I usually have a regular 28 day cycle, however I think I ovulate earlier than Glow says. I believe I ovulated on the Mon/Tues 3/4th Aug. However due to hubby's work we only got to BD on Fri 31st and then the Tues 4th. What do you think my chances are of the sperm from the Friday still hanging around till the Monday? I'm worried I've missed out this month if our BD on the Tuesday was too late to get the egg. Guess I'd just like opinions
