Anybody else’s sex life horrible?

My husband and I have only had sex 4-5 times since we found out I’m pregnant (which we found out on November 25th). Anyways though we had sex about 3-4 weeks ago and it was terrible sex. He couldn’t keep a hard on and it just wasn’t good. Then today I’m half asleep and it actually wants to have sex for once so I wake myself up and the position he was trying to do it in was uncomfortable for me and he just tells me that it’s the only position he’s willing to do it in and I told him it was hurting me that way so he turns over and just close his eyes. I’m just infuriated and just laying in bed crying now.
