D&c and d&e

I had a d&c in June at 20 weeks I had a hemorrhage and was told I would need a d&c done and I tried everything to save my baby girl and was told her umbilical cord was separating from her and I asked it I didn’t have the d and c done that we would have both passed away it was the hardest decision I have ever made it took me hours. I been trying to conceive since my first period after my d&c and still no luck. How long did it take you to get pregnant after a d&c?
