Chinese Water Dragon Eggs, URGENT!

[Mr Philips Chikin Wong]

Hi all! I got problem in hatching Chinese Water Dragon eggs.

My female finally gave a clutch of 11 eggs on Feb, after a long struggle
since last summer until I heated and warm-up the room and keep her in a
sand box for 2 days.

I then formed an incubator with a warm water bath with the eggs inside
a plastic box buried 2/3 in vermiculite with mist of water every 2 days.
Water temp. maintained at 84-86F.
Now I have only 2 remained, they should have been hatched after 65 days
on April 13 but now I don't see any symptoms. What should I do instead of
wait? I now struggle for whether open the egg or wait. ANy ideas?
I opened a dead egg before, there was an embryo inside so I assume these
two are the same and they do showed some kind of life form inside.
They grow larger slightly, still white in color, no mould or fungi found
on shell nor any change in shape.
As I can't source any professional advice in Hong Kong, please help.
