isn't the end of world but I'd check everything I could before pulling the head

While everything you say here is correct, it isn't a hard and fast rule
that coolant will get past the piston into the oil
. If it is a small leak into a cylinder then the coolant will turn to steam and exit the exhaust
. If the leak is allowed to get worse then I would imagine that coolant could get into the oil
as you state.
test is the next coarse of action. With that information you should be able to tell which cylinder, if any, is low in compression
, then with that information you can determine that the head gasket
has a leak. Having the compression information is also a great indication of general health
of the engine
. If the compression is close to factory spec's you know that your engine
is generally in good condition.
