Hi L.~
I am truely sorry for your loss. I know first hand that this can be a tough time for you and your family. There is a ton of light at the end of this tunnel though!
I too had a misscarriage (Mother's Day 07'), and I was just a little further than you were. Mine was classified as a "spontaneous misscarriage", just something there that wasn't right. I actually fully misscarried on on the ultrasound table at the ER.
My doctor gave me the green light to go ahead and try again. He advised me to wait one period, and then after that period to try again. In mid June 07 we conceived again, and on March 11th of 08 my little girl was born!
Misscarriages can be trying and heart-wrenching. Just know that they happen for a reason. Something about that pregancy wasn't right, and your body knew what to do by itself. It is truly amazing.
If your doctor gives you the green light, then I say jump back on that wagon and try again!
Many Blessings~
