   There is the difference   
   between the reactive centrifugal force   
   and the fictitious centrifugal force.   
      
   In your case, there is the centripetal force   
   pushing you toward the centre of the curvature of your motion.   
   Perceived centrifugal force is the normal reactive force,   
   just in a circular rotating scenario.   
      
   It is a different thing   
   then the fictitious centrifugal force in rotating coordinate systems.
