Do I only get charged one click per one visit?

Hi first visit. My PPC ‘seems’ very high for the number of visits, when I checked my statcounter it shows 3 ‘paid’ symbols on one visit i.e. each time the visitor returned to my home page it has the paid symbol. Can this mean I am paying 3x for same visitor – same session? Is it possible for me to check or examine my payments/charges?
