Have some patience, you will get in when you get in, and besides "Up to 5 days" does not mean you are getting 5 days, it means you MIGHT get 5 days... and this is STILL 7 days early...
I would be more worried about whether or not you will have your hard copy (for those that ordered hard copies from online retailers) on the actual release date... because up then you can play without actually having purchased the game, you could cancel your pre-order and still get to play...
SO RELAX!!!
