UK Section mummies...advice please!

Kelly
Hi Ladies, 
I'm a FTM, due June 20th, & I've been told that, due to my prior medical history, I have to have a planned section, I will not be allowed to labour at all. I'm also aware that my mama went early (35/36wks) for all her babies, so I want to try to get a hospital bag sorted out fairly early, just in case I follow in her footsteps there too )I've already had a fair amount of bleeding like she did) That being the case, I have a few questions
1. How long were you in hospital after your sections?
2. What did you pack in your hospital bags?
3. Is there anything you wish you had know before you had it? 
I really appreciate any advice or tips you can give! Thanks in advance.
