Don't be. If there is krausen and active fermentation, the yeast isn't inactive. Even if it was, there's no harm in leaving the beer on the yeast for a month plus - it can only be good for your beer.
Let it go until the bubbling stops, then take a gravity reading. Take one again the next day. If it hasn't moved, you're good to bottle.
