They can have bruising for lots of reasons, but you're doing all you can until the incubator gets here, so don't lose heart! You could probably turn it still, as it doesnt look ready for lockdown quite yet. But if you've missed a few days of turning don't worry, as after 14 days there isnt likely to be many issues caused by not turning them. So it's up to you.
Since you don't know the day it is on, I wouldnt put it into lockdown until the air cell drops, you'll notice the duckling has filled all the egg, and the cell will grow and draw down one side a bit, you may even see shadowing in the air cell-at which point you can safely lockdown.
