I had a scan today, my last period would suggest I was 9weeks + 1 day, however when I have been today for the viability scan she said I was measuring at 6weeks, there was a sac but nothing in it. Which has worried me somewhat!! Is there anyone that's been through similar that could help me!? She referred me to my local hospital to be scanned again in a couple of weeks but now I'm all worried. What if it's gone.
