They look fine to me. I've had eggs look much worse and still hatch out awesome little babies.

Being that it's so close to the hatch date i don't think it will matter, but in the future if you see the buldges and stretch marks, try lowering the humidity just a little. I seem to get that issue a lot around the midway point of incubation so i just remove the lid of my tubs for an hour or so each day until the eggs start go back to normal.
