Shift wives/SO question....help!

So my husband is a firefighter and he works 24 hour shifts, and of course I got my positive opk this morning. Thankfully, he was home when I got my positive and we BD’d before he left. But, I know that after you get your positive opk you typically ovulate 24 to 36 hours after you get the positive. I just wanted to ask you ladies what time do you find is the best times BD? I won’t see him again until tomorrow around 3 or 4pm, so about 36 hours after I got my first positive, since we BD’d today and we plan on tomorrow as soon as I see him, do you think we still have a good shot?
