Frustrated with BD schedule

I may just be in a hormonal funk but I'm seriously frustrated with the amount of BD my husband and I are having. I get so stressed out bc I will give him the dates of my fertile window and suddenly he's got too much going on. He works on houses so I understand being tired (he works hard!!). I just feel like his expectations of how soon we will get pregnant are waaay too high. I've tried explaining how much of a % we have of conceiving every month but we still aren't. Hell... we really aren't having sex even on my non-fertile days. I feel like ever since our loss earlier this year he acts weird about sex. He says he wants it all the time but I'm usually the one asking him. I just don't know what to do now. ?
