Today was the day! (I think) and I can’t do the “deed”

Pictured below are my ovulation strips, and it looks like I surged today? The thing is, my husband works night shift so it’s hard to catch us in a moment where we can try. We had sex 2 nights ago (the 11th) at about 1030 pm (he came home from work). Yesterday I left for work before he got home and got home from work after he’d already left for the night for his job so we couldn’t have sex. Tonight he says he’s super busy at work and does not know if he can leave for a little bit to come try, but we can when he gets home around 7 am. That’s 7 ish hours from now (my time is currently 11:42 pm). Do you all think it’ll be too late? Could I still get pregnant from the 3/11 session? Thanks! This is our first actual time TTC and this is the second cycle. Our other two children weren’t “accidents” but we didn’t think it would happen the first time trying either, so for me to not end up pregnant last month after having sex I. The fertile window was really shocking for me. I’m also 29, and have no idea if that plays a role in things.
