High fertility day but my DH won't BD.

Finally got my flashing smiley face on my OPK, I thought I had missed it because I had to switch brands. My husband won't BD though because he was woken up so rudely by a weed wacker right outside the window. So now he's SUPER cranky because he has to work the night shift and only got a few hours of sleep. I don't even want to bother him about it.  What should I do?
