Bubble Bubble, Toil and Trouble

Well, here's where I am so far.
I brewed an Amber Jan 20th and hit my OG of 1.052. Temps were 66-68 in Primary
I moved to secondary Feb 2nd. Gravity at 1.012. ( I've followed the 2ndary debates and still chose to move it. ) Temps for secondary were 60-62 with WL german kolshch 029.
Today, Feb 10th I was thinking of bottling... I pulled a hydrometer test for final and it's sitting at 1.012 still.

BUT here's where the question comes in.
I see bubbles in suspension. They are extremely small though. My thoughts are that I made a mistake with the hydrometer reading, ie adjusting for temps..thought I did but nothing I can do now... and it's still finishing.
Ideas?

Totally normal to have fermentation gasses in suspension, if gravity hasn't changed go ahead and package it

There's always co2 present to some extent in our fermentations. It's a natural byproduct of yeast eating sugar....Nothing to pay any attention to.

Thanks for the reassurance. I bottled and will let it sit for a couple weeks. Pretty excited to taste this one... the sample I pulled when bottling was very tasty!
