How can you tell when your eggs will hatch ??

Hello all,
I was just wondering if you can tell that your beardie eggs are going to hatch soon ??? If so how ?? what do I watch for ??

If your eggs are close to their "due date", you will first notice the eggs sweating and swelling, then, just before hatching, the egg will collapse.

Um ok they are at about 45 days the are sweating (it looks like balls of moisture on top of some of them ), but they are very veiny and you can somewhat see the shape of a dragon ( shadowed area). Will the egg fill with the shadow ? Some of them also seem to be becoming transparent.
