My battery light comes on when Im driving and then will go off after awhile.

I took it to a parts store/shop.

Lots of parts stores do (free)test...but you have to understand they are not trained technicians so the value of the test could be in question. See it all too often when folks finally come here to find out what is wrong with their car after trying all the parts a parts store suggested to fix a problem that did not do the job.

Thank for your help. I guess I need to take it to a shop then. Now I just need to figure out which one isnt gonna take advantage of me being a woman customer.

Suggest you get recommendations from friends or coworkers of a good shop in your area. I highly suspect the alternator is the problem with your car. The "repair pal" site has a estimator feature that works well in estimating common repairs. That button is at the top of this page. It will give the high and low range for your repair.
