I have a question about my 1996 olds Cutlass supreme sl 3.1

Its leaking antifreeze out of the overlfow tank, it drains in about 2 weeks, the oil isnt milky and the radiator is fine. There isnt a unusual amount of smoke coming out of the tail pipe. The antifreeze is coming out from under where the water pump is, and a little bit seems like it was leaking on the opposite side of the front of the engine, I was thinking it might have just splashed. Does that sound like a head gasket or water pump? Thanks
