You should confirm that final gravity has been reached in the primary before racking to a secondary clearing vessel. You can also skip the secondary vessel if not adding fruit, oak, fermentables, etc. The beer will clear nicely in the primary given enough time. Three weeks is my typical primary time for most ales.
Your beer may not have finished fermenting in five days. The bubbles you see in the air lock may just be CO2 coming out of solution or the fermentation trying to finish.
