Does it take longer to conceive after having a D&C versus having a natural MC?

I opted to have a D&C last week after finding out I had a MMC 3 weeks ago. I'm just curious if it takes longer to conceive after having a D&C or a natural miscarriage? We're ready to start trying again as soon as the doctor gives us the ok, but nervous about the D&C possibly effecting how long we'll be TTC for.
