I dont think im that small
Haha, I was like that too, and I always remember to ask people how they feel now - because I felt HUGE, I was uncomfy, I felt fat, ugly (you know, that's the bad days of pregnancy for you :P), and people were saying 'oh you're tiny, wish I'd had a neat comfortable package like that'.

Comments like that just invalidate how a pregnant person is feeling, I hated it, because they said it like it was praise and I should graciously accept their comment like 'oh yes, thankyou, yes I am small, I did it deliberately, and of course it's comfortable, what sane 30 week pregnant chick wouldn't be comfortable?'
Dorks.

Anyway, I'll stop having flashbacks :P and remind you again, DON'T let comments worry you if you weren't worried before and your carers aren't worried.
