By your description I suggest that you go to your local auto parts store who can perform an alternator and battery life test for you. You typically can find one that will perform these tests for you for free. You may be have a failing component in your charging system.

Hello Tiffany- sounds like you may have a bad IAC valve - go & have the charging system checked just to be on the safe side- hope this helps- thanks Super Girls Auto.
