Sounds like you had a blighted ovum, which is what I experienced in November. I'm very sorry it sucks.
I chose to have the D&C right away - I wanted it to be over. "ripping off the band-aid" if you will. You have to do what's right for you no matter what.
If you ever want to talk/vent/whatever feel free to PM. I have no problems talking about what I went through. It's nice to have someone that can relate.
