What foods are you feeding her? Sometimes they will suddenly change their minds about a food and not want it anymore, which is why a mix of 2-3 foods is recommended.
Sometimes hedgehogs will go on hunger strikes where they won't eat much for 2-3 days. It can happen because of a change, which is where the shavings would come into the picture. I would switch her back to her old bedding brand, or just make the total switch to liners. That could've been the starting point.
Since it's been more than 3 days now, however, I would guess it's probably something other than a hunger strike and a vet visit is probably in order. Sometimes an oral problem can cause them to stop eating, such as a tooth infection.
Whichever case, you have to make sure she eats. You should start syringe feeding her immediately, since it's been 4-5 days with her eating almost nothing. Here is a guide that may be helpful:

You can also find many threads about it on the forums here if you search.
It's VERY important that she start eating something immediately, because 2-3 pieces is not nearly enough.
