Body image "problem" at 24 weeks

I'm 39 and have always been very body positive but now that I'm 24weeks along and feeling huge, some insecurities are naturally coming out. I've never seen my body like this and it's new and uncomfortable, particularly when other people make comments about my size. My husband yesterday called it a body image problem... I broke down crying. How do I get him to understand what I'm going through and that is not a "problem?" How do I get him to be more positive and flattering to me? If he can't be, does it mean he sees me as unattractive as I feel right now?
