Beck1988 My very pg friend complained of this early on. Hopefully it's too weird an observation to be anything else!! Fingers crossed for you 
Cakelaur Wonderful news things are progressing. It's great the EPU offer reassurance scans, 2 weeks feels looong but (should) go quickly.
Thanks to Boboelephant, DaisyMay25, haleyfx, Daffofils86, and HidCat for the welcome and commiserations. It's great to talk about this with someone other than dh.
I've started cramping so I think I have my answer tbh. I was starting to hope a tiny bit I'd be sent for a scan and magicly there would be a healthy baby. Maybe, but probably definitely not.
