Still no shed

So My bp showed signs of shedding about 11 days ago, the blue-ing stage I thought. Her black looked very blue in the light and her eyes were silvering over. I've left her alone since than except I lifted her hide off of her about 5 days ago just to see what she looked like and to make sure she was actually shedding, and I wasn't bumping up the humidity for no reason. She was just more blue, and seemed liked her colors were dulling but because I didn't take her out of the enclosure I'm not totally sure. So I want to know how many days they stay blue before it goes away and they shed?? Because as I understand the blue will go away just before the actual shed? I want to make sure I'm not just making myself think she's shedding and she's really not.

I suggest you read this:

I've definitely already read that sticky. Thank You tho it was very helpful. But just now I got to see her out side of her hide and she is still pretty blue. So Its been about 11 days with blue. The sticky has it lasting top 6 days. So my new question is why is she still blue? Is there a natural blue tint to her scales all the time just more blue when she sheds or is she just taking a long shed? Should I be worried? Or am I just convincing myself she's shedding when she's not?
