Hi Darkdreamer, Im sorry things arent going easily for your TTC venture
Think it depends on the type of D&C you have, mine was a suction D&C and I spotted for a day, very lightly. That was it. Ive never had a hystoscopy with out a laparoscopy included (part of IVF) so I cant help you there. Are you having both or just the hystoscopy??
Hang in there hun, hopefully they can get to the bottom of this quickly and you cant start TTC#2 again

ETA: did you know you are more fertile after a D&C?
