I'm so incredibly sorry. I hope you find peace in whatever choice you make.
I had a miscarriage at home at around 8 weeks. While nowhere NEAR pleasant...I found a lot of peace through it. I've never had a d&c though, so I can't compare.
To me, the hardest part about miscarrying naturally is that it can be a very long process. I started barely spotting at 7 weeks....and went on to finally miscarry at 8 weeks, 4 days. I actually wasn't seeing a midwife at the time, so I just trusted that if that the was the end of the pregnancy, then my body would take care of it. And it did, but I really have no idea how long it took. There was no fetus to be seen...and less blood than is often described, so (after speaking with a midwife about it) I'm guessing development stopped VERY early on and it just took that long to pass it, or it was a blighted ovum in the first place.
The waiting is incredibly hard. It does feel as though your entire life is on hold...and physically, I wasn't very comfortable during that week I was waiting.
however, as I mentioned in the beginning, I found a lot of peace. I was able to participate in the process as the actual passing feels very much like early to mid stages of labor...and it left me with that same sense of being stronger than I had thought I could be as birth itself gave me. It's an incredibly personal choice though.
Oh, and I will also add that when my spotting first began, I was experiencing MS worse than that which I had experienced with my son's healthy pregnancy...and I actually passed everything BEFORE that faded. My breasts also remained extremely sore for the next two weeks following the miscarriage.
