T.W.
I miscarried at nearly 5 months and did not have a D&C. We didn't necessarily try again but we did get pregnant within 2 months of the miscarriage and it was completely successful. My doc did tell me that I did not have to wait if I did not want to. He did not indicate that there were any greater risks of another miscarriage but he did say that statistics show that it is typically pretty quick after a miscarriage that women get pregnant again.
I wouldn't over-think it, if it is meant to be it is meant to be. I would just go for it when you are done healing from this one.
Good luck to you, I know how painful it is to go through it.
