Bubbles in secondary

[VA Brew]

Here is the deal, i think i transfered to secondary a little early (8 days for a hefe) a little krausen reappeared for a couple days. No the krausen is gone and it has been 16 days since the brew date and little bubbles are rising.

Is bubbles rising in secondary well after fermentation should be over a sure sign of contamination?

just to clarify, the air lock is NOT bubbling only little bubbles in the liquid and its making little water droplets on the top of the carboy that look like condensation would.

My guess is that it some CO2 coming out of solution. I wouldn't worry much plus give it taste test.

totally normal. co2 IS coming out of solution, which is good as it covers the beer surface with a co2 blanket to prevent oxidation as it sits in secondary.
