Question: Eat rockwool

[Picificsi]

Hi!
Yesterday I saw that my 12 cm white axy swallowed a really big piece of rockwool (it is around the roots of her plants). Now, her belly is huge, but it also can be because I fed her well before it happened. This morning I gave her very little pieces of chicken liver, because I herad it helps to make axy pooh softer, and I hope this way it will be easier to push out.
Has it ever happened to anybody else's axy? Can you give me any advice please?
I worry so much, she is my little baby!!! <3
Please help!

Rockwool? As in insulation? How big was the peice?

Not insulation, it is substrate. I phoned the shop where I bought it after she ate it, and they told me what it is. The piece was as big as she could swallow it. I would say it was about 2x0,5 cm.
