Hi all, was delighted to conceived our second baby after a loss in 2018. Date of my last period was 11th October and my bfp was 9th November. I went for a private reassurance scan today and was told the sac is only 13mm (no heartbeat she said it was too small to see) whereas the sac should be 20mm according to my dates. The clinic have said I may not be that far along but surely I wouldn't have got a bfp on 9th November? I've had no bleeding and are having usual pregnancy symptoms but I'm suspecting a missed miscarriage. I have booked in for another scan on 17th December but the wait is agonising. Has anyone been through anything like this before please? Really not sure what to do sorry.
