I made a batch of the Heady Topper clone about a week before Christmas. I used Vermont Ale yeast and used a starter. Fermentation started quickly. Now it’s been in the secondary for several weeks but it still looks active. It’s pushing a bubble through the airlock about every 2 and half minutes. Last time I checked the gravity it was about 1010. So what to do, continue to wait until it stops bubbling completely? I’m feeling very cautious as I’ve had over carbonation problems 
in the last few batches I’ve made. The other thing I was considering was bottling without priming sugar, if it ends up flat I could uncap add a sugar pellet and recap. Thoughts?
Check your gravity again two or three days after the last time you checked it, if it stays the same, you’re good to bottle. I’m thinking the bubbles in your airlock are just C02 offgassing from your beer, especially seeing how long your beer has been in the secondary.
I would NOT bottle without priming, you will just end up with flat beer. I would consult a priming calculator to determine what level of carbonation you want and start there.
On a different note, welcome to the forum! :cheers:
One reason for over carbonation, beside not weighing out the appropriate amount of priming sugar, is racking to a secondary vessel before FG is reached. This can result in the fermentation being stalled and then finishing in the bottle.
Bubbling means nothing. It’s just gas escaping.
How long has your OG been stable at 1.010? That’s what tells you if fermentation is complete.
