What do i do? To bd or not to bd...

I'm in my fertile week and got my "pre-ovulation" temperature dip this morning. I know today is an important day to BD but my husband is worn out and has asked for a night "off" we have had sex the past 5 nights straight and 7 times in the past 9 days so I understand but I'm disappointed... I don't want to miss our chance and then the whole month is out. Do you think it is ok if we skip tonight? Is there a way that I can convince him? I can't tell him about it directly or else he feels pressured and we have "bedroom troubles" so it wouldn't make anything better anyway... Any ideas ladies?
