It may still be the hg, it can have a very small leak. I had a similar problem for a few months until it finally got worse. But I would stop using the heater for awhile and see if you have the same problem.

I was missing coolant mysteriously, looked under passenger carpet and found a puddle there. My heater core cracked or something
