Bottom surgery question mtf

Hi all!

I have two questions here

I'm scheduled for bottom surgery with dr bellringer on 2nd june

First I'm getting quite anxious about things that might stop this from happening. I don't have any obvious health issues but I know they do tests beforehand and I'm worried something SOMETHING will come up. Does anyone know the kinds of reasons someone could be turned down for surgery at this stage? Just want to be emotionally prepared for all possibilities...

Second question, I'm sure I won't be the only one there for surgery at that time - anyone else be there? If on the off-chance someone will be and reads this it would be lovely to link up!
