need opinions on hospital bag

Hey there everyone, I'm 29 weeks pregnant due 20th of February 2017, 
It's my first and I'm just wanting to get everyone's opinions/ ideas on when I should start getting a hospital bag ready and what exactly you need, like the basics. Because I've read and been told all these different things that you should bring, and I really don't just want to pack something that's not actually necessary.  
thanks :)))
