I actually lost a lot of blood, I probably should have had it right off the bat. I had a good D and C experience (if such exists). My only worry was any scarring from the procedure but if you are done you don't even have to worry about that. Definitely push them to have it if it seems to be dragging on.
Do you know your dates? I think I would want to be past the point where there is chance there could be a viable baby there, just to be sure. I have been thinking about you dealing with this with the three kids, I'm sure it is not easy, take care.
ps, glad you are enjoying reminding them they would not treat you, I also like to spread this around about my original clinic, so fun! I actually had to bring my dd once to the ped who was the husband of my original RE (who would not do IVF on me). I was so tempted to bring it up but I wimped out. I should have said, tell you wife hi for me, this is my dd who would not be here if I had kept seeing her.
