Okay, here goes. Sorry for the long post!
Feather massive congrats :)
Hope you have an amazing holiday weechops!
Alyssa, I totally feel for you. Woke up this morning with dreadful tonsillitis, and now I'm panicking that it's strep throat. Aah, pregnancy worries :)
You're totally right pistachio, everyone always has a bloody opinion. MIL pretty much told me yesterday that I must be a terrible person for wanting to find out the sex because it shouldn't matter and I'm going to be a terrible mum for not loving my child either way. No idea how she came to that conclusion; I'm totally 100% happy with a boy or a girl and incredibly excited, but my main priority is a health baby. Didn't really know how to respond to her.
music, I feel your pain. Get a physio referral, it really helped me when my MW diagnosed me with sciatica early on. Hope you feel better 
Queen, I know it's difficult but try not to worry - high risk doesn't mean 100% risk. You still might not develop it :)
Frouby, congrats about the pony show!! Your DD will be really proud showing them all off 
MrsShrubs, seems we missed the sun in the West of Scotland! grumble grumble, glad you enjoyed it though! :)
No advice about that awful work colleague holly but have a

I've got my 20 week scan on the 17th, two weeks on Wednesday!! Oh my god so excited, panicking slightly but trying not to worry too much. Best of luck to everyone with scans coming up soon, if I don't post before then :)
