If you entered a code before then you are fine. There are 2 codes. The pre-order code and the retail code. You will not need to enter the retail code until you actually get it, which hopefully will be before the 20th when early access ends. Multiple waves of emails are going out today so if you didn't get in the first batch, just relax and drink a cup of coffee. My Origin retail code is supposed to be emailed on the 15/16th, but my pre-order code was entered back when I got it.
