The day before surgery?

Hailie • 🎀20 years old, pregnant with my baby girl. February 18th 2016! ❤️
So i have to go in on thursday before my c section on friday.
What should i expect?
I know they have to do blood work and urine tests, also watch a video.
How long do you fast before surgery?
I have to go in at 6 am on friday just in case an opening comes up, which i doubt their will be a opening...
But my c section is scheduled for 3:45pm on Friday.
