The sonographer did the scan this morning (last night had the portable one and a doc do the scan on labour ward).
She took some measurements and said it was a little small for my dates but apart from that there was nothing obvious. She said it had died only in the past 2/3 days, which I knew already as heard heartbeat on Sat morning.
I have the option of requesting a post mortem, so I think I will do that, as I want to know.
There are lots of decisions to be made about photos, hand prints, funerals and so on which are all incredibly heartbreaking.
