I would be inclined to let it be and keep a close watch since it's so active and seems to be making progress. I see where Utah's coming from though since it's been 48 hours. Give it another 2 hours and see what happens.
So long as it is doing what it is doing... you should be fine. It is important to keep humidity up so do not open bator! If something changes, let us know and we will try to help.
Yep, leave it be and watch about every 30 min to 1 hour to make sure it's still responsive to light shown into the bator. Try and not lift the lid unless absolutely needed.
