I upgraded to the full version of Wow while my Trial was still on. Help?

So I made a trial account yesterday, and a couple hours in i decided to buy WoW, and BC. So i got all the patches and stuff and when I opend WoW again, im still on my trial. I linked the full game to my trail as well. I dont want to have to buy it again. Do I have to wait till my trial is up before I can actually play WoW? please help :)
