Morning all,
Good luck to those having their scans today. Jessie and Super - my symptoms practically went and I didn't 'feel pregnant' for a few weeks before 12wks but the scan showed I most definitely am, with 2 of the little beggars, so try not to worry. It's difficult to believe in something you haven't actually had proof of (other than a line on a stick) but you'll be seeing it (or maybe them, lol!) on the screen soon enough. Excited for you! 
Sarah -I'm like you and seem to be able to get away with washing my hair less, which is great, Looks better too, as does my skin, but nails are breaking left right and centre, which is annoying.
Seat - hope all goes well at EPU - great that you can feel the movement though, must be reassuring.
Re. walking- must admit I haven't done anything recently, not particularly due to being pg but because of the crap weather, dark evenings and weekends being spent trying to get the house sorted before June. Must admit, haven't missed it as have no inclination to go out in this weather! Went to visit parents at the weekend and the wind and rain were horrendous - went to do a bit of shopping and nearly got blown over! Did spend a while in Matalan though and got some leggings, stretchy tops and a couple of jumper dresses- think they will become my winter maternity uniform! Wearing some today and it's so nice to get out of too-tight jeans!
Jealous of talk of Baby on Board badges - I want one but don't live in London. Mind you, MIL does and DH has a couple of friends who work for TfL so might see if someone can wangle me one 
People here seem to be quite good at giving up their seats but I can imagine I'll just look fat rather than pg for a while yet!
Liquid - you're not a failure at all! As Marlena says, there's no telling when this one will arrive (assuming not a particular reason repeated) but even if it is early it's not your fault and it'll come when it comes. Don't feel bad about something which may not happen and you can't help anyway!
Hope everyone has a good week
