Ali I'm 19 weeks tomorrow too - thankfully these last few weeks since week 12 have went much quicker than the first 12!
Moomin it's normal to be worried about scans and things going wrong. There's so much information out there about everything that can go wrong, and when you want your baby so much, it's not unusual to fear the worst. I'm sure everything is fine though - I can't wait to hear how your scan went and see pics!
blanket congratulations on your daughter! Ignore everyone else. There's something about being pregnant that turns everyone else into insensitive fuckers! Hopefully you can relax and enjoy the rest of this crazy journey - sorry you've had such a tough time before x
alyss that operation sounds horrendous, but thank jeebus it's over and I'm glad things are looking up! Just take it easy and order your dh about ;-)
I hope littlebairn is doing okay. I keep thinking of her. I hope she has lots of real life support.
Everyone else, my brain hasn't got the capacity to remember more names. Hope we're all doing well. 19 weeks tomorrow and I have a vay vay posh work do on Saturday so I look ridiculous and pregnant in an evening dress. Ah well. Hopefully everyone else will be too drunk to notice!
Can't wait to see the scan news and pics coming in... Mine isn't for another week and a day. I am chomping at the bit to find out the sex! DH wouldn't let me book a private one, the arse! Told us to just wait. I kinda hope the baby doesn't let us see and we have to book a private one to find out anyway, that'll learn him not to let me get my own way! 
May the force be with us!
