Hissing roach problem

[tarantulas118]

My female hissing cockroach for some reason for the past few days has been venturing out and staying on top of her hide and that’s where she’ll stay for a long time and that is pretty weird, but, I also found out that she’s not been eating all though she has plenty of food she started getting skinnier and she is not as active as before. It’s not colder in the enclosure and the other roaches are doing fine. What does this mean
this was her just a couple of weeks ago

and now look at her

They grow and shrink.. I don't see much of a reason for it usually. They seem to eat in spurts too. Both my females should be gravid still, and they look smaller some days and bigger on others... It's possible she aborted an ootheca, she was splitting at the seams there, but no way to know unless you saw it.
