Lovely scan pictures jelly and Torfhinn.
Beano. I completely agree. Love how they all look different. 
Its been a couple of weeks since my 12 week scan so obviously I was back to freaking out today. (The next one is SO far away). Broke out the doppler and there was a horse galloping away in there. Phew!
The stats they give you about the risk of miscarriage dropping away to 1% after 12 weeks doesnt help me at all. Whats numbers compared to a live heartbeat? I am good for another week now. 
Thanks for the info on the NCT classes. I wqs wondering whether to do them too.
