Thats interesting that its most accurate on LMP. I'm as regular as clockwork, and my last pg and scan complelely concurred with dates. I was still 11days later induced, and like I say - she wasn't even a tad wrinkly.
One of the midwives at the FBU got REALLY cranky once and said - Babies DO NOT take 40 weeks - they take between 38 and 42 weeks, and thats just all there is to it.

The problem is - how many mums actually want to hang on til 42 weeks when they are already over, in summer, sick of being big and uncomfy, not sleeping at all, prelabour every single night (plus during the day), sore, tired and of course just a tad excited!

Lisa - I hope it all works out for you.
