If this is a miscarriage, how quickly will it happen?

[ElmMum]

I'm 10 weeks pregnant and starting bleeding today. Not heavily at the moment but more than just spotting, and red blood not old brown blood.

Docs have booked me in for a scan on Wed am (the earliest slot they had).

I suppose I just feel in the dark about how a miscarriage might go.

I know it might not be a miscarriage, but if it is, could this light bleeding go on for days or should I expect to start bleeding heavily soon? It started at midday today.

DH is away (he's going to come back asap tomorrow) but I'm worried that I might miscarry overnight while he's not here.

Any info very gratefully received x

Sorry don,t know how to link thread but think is under the title That's that then.Speaking on my own experiences i miscarried at nearly 16wks last week and found peoples concern very heart warming
