3 adsense ads at all ?

I'm new to adsense and i heard that i can put 3 ad units and 3 link units on the same page ?
But in my site it's letting me to put 3 of them at all, not 6 in total, 3 in total, why ?
this is my blog : http://takeyourfun.blogspot.com/

 

I think thats a limitation imposed by the blogger. But please correct me if i'm wrong.

 

my opinion, it's not work for put full limit.

 

You can put 3 ads for ad unit and link unit. Ads may not work right after your place the code on your site. You have to wait for a couple of minutes before you can see the ads.
