Yes, if it is in the airlock you could potentially have an issue, or it could happen again! I would pop it off now that fermentation is highly active, clean it out, sanitize and pop it back on. If you can rig up a blow off tube, even better. But I would definitely not transfer the beer at this point. We've all been there and it's a mess, but you are probably fine. You just need to ride it out at this point. RDWAHAHB!
