I'm sorry for your loss. The waiting is the hardest part for me when I've miscarried. With my second miscarriage I was given misoprostal to bring on the miscarriage- it's also called cytotec. I spotted heavier for 2 days- then nothing. No miscarriage until more than a month later, just ongoing pink spotting for what seemed like forever. It wasn't painful at all, but that period that came later was quite heavy and was the actual miscarriage.
I later read that misoprostal is supposed to be combined with some other medication to bring on a miscarriage, but I can't remember what that was now.
I've never regretted my two D&C's so far for resolving my miscarriages quickly and painlessly.
It's a tough decision to make.
I hope you begin to heal quickly and well with a minimum of pain, discomfort and fear.
Take care.
