I switched my URL from blogspot to my own domain, now adsense isn't working!

A few weeks ago I made the switch from having a blog with the "blogspot" URL to my own domain. Ever since, my adsense reports have counted all the hits I have gotten, but I am not earning anything from them. So far, I have about 250 hits to my new URL, but there are no earnings, or stats for the earnings. What did I do wrong?! Anyone want to help out?
