I'm assuming your airlock dried up in that time? If it was still full, I'm guessing it wouldn't have evaporated. How much volume do you think you've lost?
Your big risk is probably infection if the airlock is dry and the beer has been exposed to the air for some or all of that time. How does it smell/taste?
