The thing is, asking how are you coping is silly. You don't really have a choice, we all just have to get on with it. Life doesn't just stop if were pregnant!
I guess some people just don't really know what to say and are trying to acknowledge your pregnancy in a sympathetic way.
Round here, pregnancy seems to be ignored, you won't get someone giving up a seat or moving out of your way. I guess its cos I live in a chavvy town were evrey other woman is pregnant lol xx
