My coolant is going somewhere I do not know where. I have replace the thermostat, radiator fan motor, and head gasket, I looked at the water pump and it seemed fine. Where could my coolant be going? I am having to put in about two quarts every few days. I am at a loss and it is starting to get really expensive.

Start with a cooling system pressure test, this will show up any external leaks. Then a head check, this is a chemical test to check for exhaust gasses in the cooling system. These are the two main tests for internal and external coolant leaks.
