Need help with contamination

[mastroiani]

Hello, ive never had a contaminated beer, until now...

I've brewed on saturday, left it in the fermenter, with temperature controller.

Today i went to see if the airlock was bubbling and i saw that the airlock alcohol have decreased considerably, and probably wasnt locking the air out of the fermenter... i dont know how much time was exposed, but on sunday it was ok.

Ive refilled the fermenter and it started bubbling like a couple of bubbles every 5 or 10 seconds.

I've poured some beer to see how was it, and although it wasnt finished the fermentation, it wasnt tasting bad, but when i left the beer in the glass, it starts to form some white spots...

I cant see inside the fermenter because its stainsteel.

Do you think its contaminated?

Thanks

Nope just looks like foam to me

Your beer isn't done fermenting so the yeast are still producing CO2 or there is a lot of CO2 in suspension. That CO2 is out gassing in your glass and trying hard to form a head on your beer. Nothing to worry about.
