I'm sorry to hear of your loss.

I had no pain after my d&c, just some mild discomfort. I bled for over 2 weeks, but the first few days was fairly light. It only got heavy for a couple of days a week after the d&c (and again 2 weeks after).

I'd be inclined to give the Dr/hospital a call and discuss it with them. It sounds like it might be worth looking into.
