How long did you wait after loss?

I had 4 MCs during the last year and a half. I get pregnant after 2-4 months after MC. I end up loosing them.
My Qustion is how long after MC did you start TTC,and was it sucsesful?
all the 4 times my doc gave me the green light to start.
All of them stop grwoing before i has bleeding. I did all the blood work and an X ray, there was no proplem found.
