I've had several beers (usually bigger ones) that were still venting a little after two weeks, but only your hydrometer can tell you if it's done. If you plan to secondary, I'd wait until the end of the second week and check the gravity. If it's good, rack it. If you're not going to do a secondary, just leave it 3-4 weeks and check the gravity and bottle if it's good. Either way it's not done right now, and even if it wasn't still bubbling it's too early to do anything.
