TTC after MTX, would you take the risk?

I've read all the articles and the overwhelming medical opinion seems to be to avoid ttc for 3 months/2 periods so that your body can build up its folic acid reserves enough to support a new pregnancy.
 However, I've seen so many ladies ttc & get pregnant immediately afterward (not on Glow, found several people on Instagram and other ttc forums online). I'm saying like just a month after MTX. Eager as I am to start ttc again, I'd rather not take a risk of harming my next baby in any way, so I'd rather wait if there's the smallest risk I can avoid. Thoughts?
