I accidentally removed my iPad Mini from my Apple ID's associated devices. How do I link it back?

Question

The account page in the App Store on the iPad says "Enabling Automatic Downloads or downloading a previous purchase will associate this device with your Apple ID for use with iTunes in the Cloud." I have done both tasks (enabling automatic downloads and downloading a previous purchase) but my iPad Mini still won't appear back on the "Manage Devices" page.
I have also read this KB: http://support.apple.com/kb/HT4627 and it said this: "Once a device or computer is associated with your Apple ID, you cannot associate that device or computer with another Apple ID for 90 days. You can view which devices or computers are currently associated, remove unused devices or computers, and see how long before they can be associated with a different Apple ID from the Account Information page in iTunes on your computer." I have never used a different Apple ID other than my account, so I don't see why I cannot re-associate my device to my ID. I also can't see the number of days before the device can be associated to another ID, because the device doesn't appear on the "Manage Devices" page in the first place. I would also like to note that my other devices do not show some sort of countdown, either.
Hoping for something to solve this! Thank you in advance!

Yeah, I guess I'm left with pretty much no choice. I do hope it appears tomorrow because I'm a bit obsessive-compulsive and not seeing it there with my other devices bothers me quite a lot, as silly as it may seem. Thank you, though!
And BTW, if I follow M1SSB's advice and restore my iPad, would it delete everything? Because when I clicked the restore button, it said I had an option to restore contacts and etc after going back to factory settings, but does that mean all photos on the iPad would be gone?
