"you don't look very big"

Danielle • Engaged to my best friend and first time mother to my precious boy x
I always see people being offended at being told "you're massive" (and I totally get it)... 
But I'm 23 weeks and constantly get reminded I'm not very big to say I'm over half way!!! 
Does anyone else get totally offended by that? It makes me feel like my bump is inadequate or that things aren't developing right!? 😫 is this a real stress or a hormonal rage?!
