Hospital bag

Hello ladies!! I'm two days shy of 30 weeks and for some reason I have a gut feeling ill be having my baby girl wishing 6 weeks. She's been sitting extremely low for the past 4/5 weeks now and the pressure is becoming more intense as the weeks go on. I'm praying that we make it close to my due date which is July 21st but I think she has other plans lol. Is it too early to pack a hospital bag? And what are the absolute necessities that should be in there?
