Sounds completely normal. The yeast should be highly active the first few days then the activity will slow down as the replicating/ budding and fermentation nears completion. The next few weeks the gravity will drop a point every day or two until finally the gravity becomes final and will hold steady (for at least three days). Don't rush the process and be patient from here on out. Even with a lack of activity in the bubbler the yeast is still active and cleaning up your brew. Also don't be tempted to peek, gaze, smell, or dabble with the beer with the lid off. Just leave it in the fermenter for at least 3 weeks and then a gravity check.
