I've had two miscarraiges, two d&c's. My first m/c was at 10-11 weeks. I started bleeding on a Saturday, and went to the ER. They couldn't give me a conclusive answer (or didn't want to,) and sent me home. The next day, a Sunday, I started bleeding heavily, passing clots, and hemmoraging. I was losing huge amounts of blood, and by the time we got back to the hospital, I was very close to passing out from blood loss. They did a d&c right there in the ER to finish the process and stop the hemmoraging.
My most recent m/c was in 2007. I was 13 weeks pregnant when I found out that I wasn't actually carrying a fetus, it was a blighted ovum. I was working with a homebirth midwife, and given lots of options, including waiting it out, or working with an ob to do the d&c. Because of my previous history, and because my body was showing no signs of miscarrigae, I opted for a d&c in a controlled environment, under genral anesthesia, so I knew that I wouldn't have to go through the drama of another emergency hemmorage, d&c or whatever.
IMO, women dealing with the loss of a pregnancy should be presented with all their options, then left to make the decisions by themselves. are d&c's always medically necessary? Probably not. But could they be necessary for a woman's emotional health and greiving process? Absolutely. And I think that's just as valid a reason as a medical one, especially when you're talking about something as potentially painful as a miscarriage.
