People still don't realise I'm pregnant unless I tell them and I'm just over 22 wks.
All depends on your build etc - I'm measuring the right size, but as I started with a really flat stomach and good abs, it looked as though nothing was going on until just the other week.

It gets annoying when people keep saying how small you are though - some have asked if I'm eating properly or trying to 'hold it in'!!!! AaarrrggghhhH!!!!
