high risk? one kidney? Advise please

ka
Hi, has anyone on here been pregnant with large abdominal scars. I had cancer when I was 3 and had my right kidney removed. I also have a scar under my belly button. I am worried about what will happen when I'm pregnant.( Not pregnant ATM)  Will my stomach be able to stretch?! Would I be considered as high risk with only 1 kidney and scars?  I would love to hear any scar and pregnant story's. Thanks xx
