Hi!! Sounds like you may be having some babies!!
Have you seen a nasty gooey type of poop anywhere in her cage?? thats the plug it usually comes out before her birth a lot like women do

this is the "pre-waxy stool" and it looks like it sounds. this should show up 2-3 days before birth. you will notice her being really restless and active for 1-7 days while the mass moves down her body. If she looks really under weight in her top half that usually means she is well done and will have a big healthy litter. She will stretch out as much as possible usually on the cold end. You will see her go out in a S shape and you will see contractions begin.
