Pregnancy, nausea, and sex.

I'm 7 weeks pregnant, for some reason my husband suddenly really wants to have sex, like really bad, but I keep denying him because of the horrible nausea and he keeps pouting in a way thats making me feel like an asshole for not wanting to have sex with him... It's not as if I'm not attracted to him anymore, I just don't wanna get shaken up and potentially throw up during sex...

And I literally just ran out of the room like 30 minutes ago and threw up (that early pregnancy throw up my mom always talked about, the yellow bitter tasting shit) and he apparently didnt even hear it, even tho it was violent and literally right across the hall from our bedroom. When I told him I did in fact vomit, and very violently at that, he looked at me like I was making it up as another excuse not to have sex with him....😭 I'm very lost and emotional and I don't want my husband thinking I dont want him and I wish he'd understand...
