It's only been fermenting for 2 days and it's at 1.012? Then your fermentation isn't stuck it's doing great.
Stopped airlock bubbling doesn't mean a stuck fermentation. It means
that there is simply not enough co2 to need to be vented by the airlock. The airlock is a VENT not a fermentation gauge.
Get out of the habit of thinking the airlock is anything other than a vent to release excess co2 and you will be much happier. Your beer/cider/wine/mead will ferment whether or not the airlock bubbles.
If your airlock was bubbling and stopped---It doesn't mean fermentation has stopped.
If you airlock isn't bubbling, it doesn't mean your fermentation hasn't started....
If your airlock starts bubbling, it really doesn't matter.
If your airlock NEVER bubbles, it doesn't mean anything is wrong or right.
Your airlock is not a fermentation gauge, it is a VALVE to release excess co2. And the peak of fermentation has already wound down, so there's simply no need to vent off any excess co2.
You don't need to do a darn thing, everything is fine.
Just leave your beer alone for a couple of weeks, many of us leave our beers in primary for a month, then bottle. We only secondary if we are adding fruit or oak.
If you are secondarying leave you beer alone for two weeks to let the yeast finish and clean up after itself.
