When is it ok to start ttc after a miscarriage??

Melissa • 37, FL Mother of 3 (👧🏻👦🏼👼🏻), rest in peace my sweet baby boy 8/3/17-11/24/22 💔
I know I'm not the only one wondering this, but when is it "safe" to start trying again? I had a miscarriage on 6/18/16 at 6 weeks.. My doctor told me to wait at least one cycle and then I could start ttc again!! I have read know of people who waited 2 weeks and started ttc again.. My concern is the fear of miscarying again because its too soon?? Any takes on this? Anyone?
