Post lletz - wait for follow up smear or TTC?

Hi, i had a lletz treatment a few days ago for cin 3. i dont even have the results back yet so jumping the gun a bit here, but i wondered if the results come back with clear margins and they got all the cells etc (fingers cross this is the outcome!!) and that the next step is the follow up smear in 6 months time... do i wait for the follow up smear or do i try to have a baby as i planned to before this all happened? I am concerned if the follow up says i need more treatment this will increase the associated risks with having a baby.
