Is my water pump going out?

What is your question?

My solstice gxp turbo 2.0L leaked about 1 1/2 cups of antifreeze a couple of days ago. I didn't have any problems while I was driving, no overheating or anything. I parked the car and then a couple of hours later went out and saw the fluid. Since then, I haven't seen any leaking and the fluid level is fine. If the water pump were going out, wouldn't it leak continuously? I wasn't driving the car any differently than I do any other day. I looked under the car and saw water dripping from the metal bar/axle that runs from wheel to wheel. It was just to the right of the center. I haven't seen anything leaking since. (that happened two days ago). Thanks for any assistance.
