Got my Downs results yesterday, low risk here too. :) Though not huge numbers, more like 1 : 1,200-ish. Can't remember exactly, but it was a smaller chance than I should have for my age, and less than 0.1%, so I'm happy with that!
LittleBairn, maybe write and tell your PIL that the doctors are monitoring you closely, but that there were no major concerns raised from the scan and everything is fine with the baby?
Nausea is back a bit today, here. Bleh! Caused me a bit of grief yesterday evening as well. Looks like I'm not completely out of the woods yet, but hopefully it'll be gone soon and I'll be blooming by Christmas. 
I'll be going back to work at 9 months after the birth, like I did last time. So will need to make sure I have a nursery place arranged for the new LO by then! DD will be at school, so just need to make sure she has wrap around care.
I'm a bit strange in that I think I make a much better WOHM than I would a SAHM! I'm much better spending quality time with them at weekends and evenings, while giving them all the fun and opportunities at nursery during the week.
Probably just as well, as it's not like I have a choice anyway.
I'm the breadwinner for the family (just) and we need both DH and my salaries to get by!
