You missed the best(or worst) part, where she shits and pisses in bed:  so when she needs to make it happen she goes to the bathroom. The issue is that she at some point developed a... sort of leak? I don't even know how to describe this. It's not actual poop, she's not having a full-on bowel movement in her pants, it's some kind of semi-frequent liquid from that area like small amounts of poop but in water form. And that is sometimes in her underpants or on her towels or linen when I do laundry.
