Really! I never knew that. I so hope that’s her issue. No no gnashing, but can feel movement, but maybe that’s the digestion as you said. She’s really chunked up, but I guess she was young when I got her. This is so nice to know that there is still hope she won’t have to go through it all. Thanks for sharing.Pig stomachs move because they're digesting food. At this point, you should be able to hear the pups' teeth gnashing, and feel definite kicking if you put your hands along her flanks. If you don't see/feel/hear both those things, it's likely she's not pregnant.
