junebaby, my heart goes out to you. I went through something very similar a month ago. We'd had an early scan and the baby was there, with heartbeat, at 7 weeks. Then I had a little bleed (not much, just pinkish-brown) at 10 weeks and went to my GP who referred me for checkup scan. Scan showed development had stopped at 8 weeks, and there was no heartbeat.
Here's what happened next, hope it's useful for you:
The bleeding had stopped, as yours has - I wasn't sure what route to take, and was stunned by the whole experience. I went home to think it over, then hey presto the next day started to bleed bright red. I do wonder if knowing I was going to miscarry triggered the start of the process. Because it seemed to be starting on its own I opted to just leave it, and let it expel naturally.
There was about three days of thin, steady bright red blood and then on day 4 it was like somebody turned a tap on - went through a maxi night pad in an hour, easy. I ended up being driven to A and E by my DH because I had a lot of pain (please don't be scared by this, it's not common to everyone as you can see from above posts) - the hospital staff were absolutely lovely and gave me heavy-duty painkillers which completely sorted it out. They also gave me misoprostol to speed up the process. It took a few days for everything to pass. I didn't spot anything recognisable. Afterwards I bled at an 'average' to light level for about a week. I've just had my first normal period, just over a month after the MC.
If you're going to wait it out naturally I would say:
-Make sure you're somewhere safe and secure. I went to work, having no idea what to expect and feeling I couldn't take time off - in retrospect I should have stayed at home once I started bleeding! Take all the time you need.
-Stock up on maxi pads and painkillers (though the early stages of mine was just like period pain, and it may be no more than that.)
-Have someone with you for reassurance, or at least easily contactable who can drive you to hospital if you feel you need it.
-Don't hesitate to go to hospital if you feel you need it: if the bleeding is very heavy, or it's very painful.
The advantage of a D&C is that it's all over when you choose it, with a minimum of mess. I really don't know which I'd choose if it happened again.
I've just re-read that and it sounds a bit brutally practical (and possibly TMI)- but I hope it helps to give you an idea of what the process might be like. And I'm terribly sorry that all this has happened to you and your DH.
