Do you mean you have had no impressions or clicks registered in your adwords reporting or with your AW reporting.
If you mean in your adwords reporting, then I would guess its just a reporting lag in the system which I find sometimes happens with new campaigns.
If AW, then i'm not sure they have reports for the number of clicks. I might be wronf there though.
