Give it a week or two then check the gravity with a hydrometer. In a few more days check it again if you get the same readings the. Your fermentation is over and would be safe to bottle. If the readings change. Wait a few more days and check again. Bubbles in the airlock mean nothing but bubbles in the airlock. Airlock a will bubble due to a large range of variable. Temperature, barometric pressure, bumped the carboy/bucket knocking co2 out of suspension etc etc. airlock activity is no gauge of fermentation.
