I think you'll be fine, although I would have waited longer. You don't mention what the gravity was prior to allowing your beer to warm up. That should be your key -- you want the gravity to be stable for a 3 day period. Keep in mind that a lager is going to take longer to ferment than an ale, due to the lower fermentation temperatures.
