My first miscarriage I had a D&C. I had a second miscarriage 6 months later and did NOT have a D&C. We had moved so it was with a different doctor. I got pregnant a month after the second and that pregnancy was fine. Both miscarriages were at 5 weeks or so. I have sort of regretted the D&C I had the first time because it I felt it was "unnatural". My first miscarriage I found out at the ultrasound and the second miscarriage I started bleeding. Maybe that was the reason for the D&C for the first - to expel the pregnancy because it wasn't expelling itself. Good-luck.
