would you just take a gravity reading and figure out where the beer is at?
the yeast cake is probably gassing off co2.
swirling the fermenter just helped it do that so your airlock, which is just a vent for the co2, bubbled some.
if you want to know if your beer is done or still needs time you need to take a gravity reading.
ignore the airlock. get a wine thief. pray some starsan around the lid. pop the lid. grab some wort with the sanitized wine thief. close the lid. dump the sample into the plastic tube your hydrometer came in and gently place your hydrometer in there. correct the reading if the temp isn't 68*. taste the sample.
