I'm so so sorry @MgW1 I've been there. It's cruel that this happens.
I remember finding out I was pregnant and then looking into buying a new car to fit the kids in as current one too small and the next day it was over - I couldn't get my head around it. Didn't even know that this could happen this early.
I don't know what it's classed as sorry. I remember telling my GP I'd had a chemical pregnancy (after googling) and she had no idea what I was on about she called it an early miscarriage.
Glad to hear you can get a scan to find out what's going on as hopefully that'll help and give you a solution. You're getting pregnant which is amazing it's just holding onto it and hopefully they can rectify this. Fingers crossed for you xx
