Pregnancy Sex Drive Help!

So, it doesn't prolly help we work opposite shifts. Him days and me nights, and I am almost 30wks pregnant. I just don't have energy for or anything physical these days, I feel bad, and he understands/gets it but still I do miss the intimacy but I usually am ready for bed before he is.. Anyone ever get in like a funk when pregnant, what did you do to get your sex drive up?
