How can you tell if you still need a Dand C after having taking Cytotec?

I am so sorry for your loss. I truly do not think there is a way to tell, it depends on how far along you are what "products of conception" you are trying to pass. (i.e. gestational sac with anembryonic pregnancy) You should go back into your doc for a ultrasound that will tell and let you see what is left, if anything, in your uterus. Good Luck.
