SO too tired to BD! Missed window?

When my SO is under a lot of work stress or exhausted from working all day it is very hard to get him to BD! I am always in the mood and the rejection is hard! We BD on Saturday and Sunday and I got a positive ovulation test on Tuesday(only day I tested)! Of course he was too tired Tuesday and Wednesday:( Have I missed my window of opportunity? Been TTC since January for #1! Any help would be appreciated!
