I think you're still ok, and you're getting real close. Since the yeast is still active, I wouldn't worry about the dreaded autolysis just yet.
What yeast did you use? How close are you to hitting the expected attenuation?
To wager a guess, I'd say maybe 7-10 more days, then go ahead and rack it. enough yeast will be left in suspension to finish fermenting the last couple of points, if your yeast is up to it.
