Sex advice?

Need some help here. My husband and I are trying to conceive and its been hard to get timing and scheduling to work with ovulation. His work requires him to be away for 3 to 4 days a week. On top of that his libido is higher in the morning than at night, to the point that when we go to sleep thats all he wants to do. I am the direct opposite, I am not a morning person whatsoever. I prefer sex at night before we go to sleep. So any advice?
