Feeling unattractive

So I’m 36 weeks pregnant with my first child. I can literally count on one hand the amount of times my husband and I have had sex my whole pregnancy. It became a little painful when I hit 20 weeks but it seems like even before that he wasn’t interested. I’ve brought it up to him that I feel unattractive and gross, he tells me nothing has changed yet he still doesn’t try.

I should add I have a lot of anxiety and self esteem issues with how I look and pregnancy has been really hard on my mental health considering I gained a lot of weight before I got pregnant so I’m the biggest I’ve ever been and it’s really not helping.

I guess what I want to know is if it’s normal for my husband to not want to be intimate with me while pregnant or is there something wrong.
