I don't see anything by what you are saying to indicate that your fermentation actually was stuck. All I see is that your airlock stopped bubbling, and that you didn't take a gravity reading because you can't with your conical.
BUT without a gravity reading all you are telling me is that your airlock stopped bubbling....That is NOT the samething as a stopped or stuck fermentation.
Whether it's in a conical, a bucket, or a carboy, it's the same thing. An airlock is a VENT, a VALVE to release excess co2, nothing more.
If it's not bubbling it just means that there no excess co2 to be vented out.
In your case, more than likely the big "bang" of fermentation is done and there's no excess co2 being voided out. It may or may not mean that fermentation is complete or is even stuck. But you can't no that just by an airlock.
It may mean that the majority of the fermentation is complete, but the yeasties still have a few points to go, just not active enough to blip the airlock.
That's why you need to take a gravity reading to know how your fermentation is going, NOT go by airlocks. The most important tool you can use is a hydrometer. It's the only way you will truly know when your beer is ready...airlock bubbles and other things are faulty.
The only way to truly know what is going on in your fermenter is with your hydrometer.
Like I said here in my blog, which I encourage you to read, Think evaluation before action
you sure as HELL wouldn't want a doctor to start cutting on you unless he used the proper diagnostic instuments like x-rays first, right? You wouldn't want him to just take a look in your eyes briefly and say "I'm cutting into your chest first thing in the morning." You would want them to use the right diagnostic tools
before the slice and dice, right? You'd cry malpractice, I would hope, if they didn't say they were sending you for an MRI and other things before going in....
Thinking about "doing anything" without taking a hydrometer reading is tantamount to the doctor deciding to cut you open without running any diagnostic tests....Taking one look at you and saying, "Yeah I'm going in." You would really want the doctor to use all means to properly diagnose what's going on?
In your case I would wait a week and take a reading, it's only been two days, so relax.
