Is it possible?

Based on opks I believe my peak was the 23rd but we couldn’t BD until the 24th. So is it possible I could still get pregnant? We work opposite schedules and aren’t home together very often so it makes trying for a baby hard 😕 he keeps saying if we don’t get it this month, he’s waiting up all night for me to get home so we can BD more often but he’s already sleep deprived so I don’t want to see that get worse, but we really want a baby 😅😅
