HELP!! Sex life problem😩

My husband and I have always had a really healthy wild sex life. I found out I was pregnant August 28th and literally since the day I found out I have just been so not into it AT ALL! I feel horrible because I’ve basically cut him off and when I do talk myself into letting it happen I practically just lay there and that’s clearly no fun for either of us. Like I said before I’m never into it like the thought of it literally makes me sick and yes I’m still very much attracted to him in all sense of the word, sometimes I have sex dreams about him but I still can’t bring myself to actually do it... help! Someone tell me this is normal and it will pass😩😩
