If you want to err on the side of caution, have the engine pressure tested.  They put pressure on the radiator overnight and see if it holds.  If not, can be a bad head gasket, cracked block, loose hose fitting, etc.  But check over the engine compartment yourself.

Small amounts of antifreeze entering one or two cylinders from a head gasket leak may not show up in the oil.

Please let us know what you find out.  This can help others who may have the same symptoms and helps build an "experience library".  Best of luck.  A head gasket is not the end of the world, head must be removed and a new gasket installed.  Labor, not parts, is what gets you as a lot of stuff usually has to be removed and reinstalled to do the job.  Make sure that quality parts are used and the the head is checked for flatness before reinstallation.  If needed, pay for the mill work to true the head.
