I was out of anti freeze this morning. I put in a new thermostat and more anti freeze. I drove it around. I checked under the car and no leaks on the ground. I checked around the head gaskets and no leaks and all the hoses and no leaks. I checked the oil and it was fine. I started the car and smelled the exhaust and it was fine also inside of the car with no smell.

If you had coolant leak out, replacing the thermostat didn't fix that. You need to pressure test the cooling system to determine where that coolant went. Bad head gaskets don't leak externally. The leak into the combustion chamber most of the time.
