D & C the right choice?

I found out I had a mis-miscarriage on November 18th, and have yet to have any cramping or signs that it's leaving my body. My husband and I are/were devastated. I was at about 6 weeks or so and my doctor says I should get a d&c. I'm terrified but my husband and I want to start trying again as soon as we can. I want to pass the miscarriage naturally but I don't want to wait any longer without any symptoms and am scared of having the d&c. Any help would be greatly appreciated.
