I was looking out for your post hun, and Im sorry to see you were felt a bit disappointed by it. I know some places will book you in for a re-scan on a different day if baby doesn't co-operate so thats a shame. I know they arnt the cheapest of things, is it not worth putting a complaint in and seeing if they offer you back? Yay for Baby M weighing 2lb 11oz though! And brill news that the placenta is no longer low lying.
We have our 3d scan on Friday, will let you know how it goes x
