I have a tiny line just above the top of my pubes. It is barely noticeable, if you're not looking for it you won't see it.

I would suggest that you look at c-section photos on The Shape of a Mother.
I think that every mother should look at that site at least once just as a counter-point to the air-brushed celeb mothers that we usually compare ourselves to.

I'm pretty sure I waxed prior. I certainly wasn't expecting a c-section so I did the gardening as usual.
