Hi Sweetie!! We've missed you.
When it comes to losses, unfortunately just like everything else in our messed up TTC lives, there's simply no one answer. Some of us will have normal cycle while others will experience a bit of a hiccup before their bodies get back to normal.
I've never had a D&C, but from over at TTCAL I've known many ladies go through the after effects of a D&C, and it seems like no two experience the exact same thing. But I will pray that your body doesn't throw you any curve balls.
As to when to start TTC again, I would allow for at least one cycle to make sure that all is as it should be. It gives your body a little time to heal, and helps you prepare mentally for the return to the journey. But I will say that many of the ladies don't wait much past one cycle.
Why don't you go over and introduce yourself. They're absolutely wonderful and you may find comfort in hearing from so many who completely understand where you are coming from.
