This sucks

I feel like my husband doesn't get that I'm pregnant. He continues to get upset because I get so tired. Or I'm hungry one minute but the minute I smell something Im nauseated. As many times as I try to get him to understand what happens in the first trimester alone, he just doesn't get it lol. And don't get me started on sex, it's the last thing on my mind and the first on his. 
Just ranting
