Good luck trying. They said "Up to 5 days", which doesn't mean you will get 5days early access. It means you could get 5days early access, depending on your pre order date. Thats been up there for a while now, do not blame Bioware for your own mistake.
Hoping to get 4th wave today, unless I get hugely lucky and they let in an ocean in the 3rd wave. xD
