No sex for me

Feeling pretty down lately. We are trying to sell a house and get ready to move. I’m pregnant and our daughter just turned two. I feel like my husband couldn’t care less about intimate time with me. I’ve mentioned it a few times because I want to but he just sighs heavy and says, “ok” or “I’m tired”. So I am totally put off then because who wants to force her husband to have sex? And of course now I feel like a giant unattractive cow.
