Pixie - with my early scan at 9 weeks they took all my GP details first and if there had been anything wrong, they would have then passed everything on. I guess it will depend on where you are and what relationship the scan place has with the local hospitals. Something to possibly call them and check if you are nervous. My scanner was a Sonographer who did them in her spare time and worked at the local EPU the rest of the time. So felt that she'd have been able to sort me out if there had been anything wrong.
Blackholes - sorry you are having a pants day, if you've not left already - GO NOW and leave the mess til tomorrow! Otherwise, consider Saturday (or next day off) as your true birthday. It's DH's birthday today and I have only remembered now I have forgotten to order his present from me - have lied and said it's been delayed in post (it's an awful print he likes - I hate it but it's the only thing he wanted)
Jess - hoping you are sitting with your lo right now or will be soon. looking forward to birth announcement!
Saggy - Fab news!! very glad to see you on here 
Books etc - I read Gina Ford before having DS - I knew I wasn't organised enough to stick to the timetable but it was useful to have some sort of plan. We have bathed DS everynight since we brought him home as a bedtime routine and it's pretty much worked. Super Nanny book was good too as is the Slummy Mummy guide.
My favorite one is by Lucy Atkins "Frst Time Parent" link here to amamzon - as it has a good section on the first few days back at home. I've given this as a present to my friends a few times.
But don't buy these books! Library will have them all and you can then decide which ones you like.
Second time round I feel so much more relaxed - this one will probably be completely different to DS and will just have to work him/her out day by day.
You will learn a new mantra post birth "If it works, don't knock it" - if you need to use dummies - use them, if you can't manage to BF or BF exclusively, then FF or mix feed, feed to sleep if you have to, buy ready made meals etc etc - whatever helps you get through as sanely as you can!
sorry epic post - rare mn on laptop today!
