Sorry ... I found the answer ... I'm having such a low visitors number that it's normal that the CRT oscillates a lot
First, tell you friends specifically not to click your ads. Maybe they have not already, but you don't want them to moving forward. Secondly, email the AdSense team to let them know you are concerned about it. It lets them know you are watching and are willing to report discrepancies. After that, sit back, relax, and watch your earnings grow. And $30.00 in the first 7 days? Congrats, thats awesome!
Thank Alejandro, I thought I was making a reply post to my own tread by I edited it instead, sorry for that and thank you for the help, I'll do as you say.
