Missed M/C & Stopped bleeding after a week...

Sam • 🇬🇧 UK Full Time Mum, 2YO girl, pregnant with 2nd
I've been bleeding like a period for a week now. Found out I had a missed miscarriage on Monday. The foetus had stopped growing about a month ago and shrunk to 3mm, the sack only measured 2.5cm.
Is it possible that I've passed it all having bled for a week? I haven't had any pain though :-/
I have another scan booked in for next Wednesday, I was gonna book a D&C for the day after.
