Loads of really good NCT opinions, thank you everyone! I think we will end up going for NCT, though I do still think it's basically just an expensive way of (hopefully) making some new friends. But I think it may be a good way for DH to meet some other dads, and I'm really not looking forward to baby groups (walking in to groups where I don't know anyone, eek!!), so I think having an NCT group will help me to feel less isolated. But we will have to save some pennies! And as one of my friends said, the key about NCT friends is that they have babies exactly the same age as yours, so you're all going through the same things at the same time, so the support/sanity saving aspect is massive.
Lovely scan pictures everyone, it's so nice to see everyone's beans growing 
Amy sending positive thoughts your way... and as you say even though the odds seem scary, in actual fact the odds are really on your side, and chances are everything will be fine.
Rose I haven't thrown up once since Monday, perhaps my body was just getting the rest of the sickness out of the way! I still feel sick, but loads better than before. Fingers crossed!!
And oh my goodness, I've been thinking about dippy eggs with soldiers for ages now, I don't even like that normally! Maybe I'll treat myself then in lion stamped ones are ok.
