D and c today...

This is my first pregnancy and sadly has ended with a mmc. I was supposed to be 9 weeks 2 days when I went in but baby only measured 8 weeks and 4 days with no heartbeat. I opted for the d and c because I think naturally miscarrying would be too hard emotionally for me and I just want it to be over. It's already been a week since we found out it was a mmc and this last week has already been torture. I'm very nervous and scared for the procedure today. I think mostly because they will only be numbing me up and not knocking me out for the procedure. I hate that I have to be awake for it! To all of you who have gone through one, what should I expect? I'm so nervous and emotionally strained already. It's going to be a tough day for my husband and I. It had only been a short time but we already loved that baby so much.
