I recently died my hair from brown to red and it is a non permanent color which lasts through 28 shampoos. I'm planning on going to a pool party in a couple of days and I was just wondering that if I go swimming, will the chlorine change the color and if so, what to?

Yes, chlorine can effect artificially colored or lightened hair. You may want to apply a conditioner on your hair and wear a swimming cap before going in the pool.
