I recently passed my motorcycle test (Category A2) but...

Hey,
After passing my motorcycle test on the 5th of Decemeber I opted to send my licence and certificate to the DVLA myself, rather than the test centre doing so as I wished to update my photograph also. I spoke to the DVLA about 20minutes ago and they have not received my licence yet. Luckly i did make a copy of the Pass Test Certificate (in case it was to get lost in the post, as this would require me to take my test again) but I am wondering if I am even covered/allowed to ride my motorcycle. The DVLA did mention that it could take 15 days to return my licence and I understand that the postal service is very busy at this time of year. I have been instructed by the DVLA that I should carry the 'blue form' around with me should I get stopped by the police. The only problem is I don't have a blue form; anyone know what form I should have, what it looks like etc..?
Thanks in advance,

Dizmo.
