SilkkBrew is right! You should rack your batch to another container and let it sit for at least a week before you bottle it! It's called Secondary Fermentation, and while your yeast might be done turning the simple sugars to alcohol, they are still alive and well, eating away at the more complex sugars. Your gravity will more than likely go down a little bit during secondary, but much more slowly.
Another thing you are doing during secondary, is getting the beer away from the crud (called Trub) on the bottom of your fermenter. You don't want to accidently siphon that into your beer bottles when you're ready to prime the beer and then bottle it.
I highly recommend that you rack the beer and let it sit for another week.
