Oh noes, you are relying on airlock bubbling as a meaning of something!!!!!!!!
Don't
Remember, you should never use a cheap chinese plastic airlock as a "fermentation Gauge," it's not...It's an airlock, nothing more, a VALVE to release excess CO2, to keep from blowing the lid off the fermentor...If it's not bubbling that just means that there's not enough CO2 to climb out of the airlock, or the CO2 is just forming a nice cushion on top of the beer like it's supposed to, or the airlock is askew, or it is leaking out the cheap rubber grommet, or you have a leak in the bucket seal...all those are fine...if CO2 is getting out then nothing's getting in....
Over half of my beers have had no airlock activity...
The only gauge of fermentaion is your hydrometer. And it's too soon to worry about it. Wait til 10 days after pitching if you want to bother checking then...
More than likely fermentation is winding down, hence the bubbling slowing down...the co2 isn't trying to escape...now let the beer sit for a few weeks to clean itself up and all is well...
This is a good blog to read....

If you are going to secondary (though most of us don't we leave it in primary for 3-4 weeks) you wait til the hydrometer hasn't changed for 3 days...usually around the 10th day after yeast pitching..
