Thanks for all the positive thoughts, all good news at my scan today.
My placenta has moved up to 8cm away from my cervix so nice and clear for a normal delivery. 
Baby has also moved to head down. The lady said it will still rotate a lot but will probably stay head down now.
Stand all measurements were about on the 50th centile line, slightly bigger head and tummy, slightly shorter legs, weight exactly average. So now I can wash all the newborn clothes as hopefully means it shouldn't be a whopper...
And the sonographer didn't let the sex slip and told us when to look away which is good as I thought things would probably be much clearer this time.
Umlauf, our baby looked a bit alien today with huge eyes and puffed out cheeks. I am sure they will be gorgeous when they are born.
