Cytotec for incomplete miscarriage?

Becca • Dance and theater teacher, who loves cheese, being outside, and fuzzy socks. Beyond excited for my Rainbow Baby after a miscarriage earlier this year.
I began miscarrying on June 4th. I went to my Dr. today and they said there is still some tissue left. It isn't enough to need a D&C so she prescribed vaginal cytotec, saying it would help my body get through this faster. Has anyone taken this for an incomplete miscarriage? I'm nervous about taking it and since there is only some tissue left I'm considering just letting my body finish the process on its own. On the other hand I've been cramping for 5 days and ready to be done.
