How Long should I wait to TTC after D&C? Anyone gets pregnant right after D&C?

I had a missed miscarriage at 15 weeks. I was pregnant with twins girls. I had undergone D&C; on 21/12/2017. The doctor told me that I shall wait for one cycle and not to have any sexual intercourse until my next AF comes.

My husband and I just could not wait any longer after I had the miscarriage and hope to try as soon as possible. Hopefully next pregnancy can ease the grievance of my loss.

Anyone has gotten pregnant right after D&C; with a healthy baby?

I also have also done home pregnancy and ovulation tests recently, both results show positive at the same time. Anyone experience this before?
