Hi Soul,
I've looked into this too. I was told by the registrars in hospital to wait a minimum of 6-12 months before ttc, because I've had 2 c/secs (like you), to make sure the scar is well & truly healed. Another OB told me, off the record so to speak, that as long as it was at least 3 months no one would be too worried. HTH.
