I remember that early in my first pregnancy I smelt soooo bad. Even the dog (who certainly didn't smell like roses herself) would look at me in disgust, turn around and walk away.
PMSL Arte!! I (unsuccessfully) tried to blame our dog for mine on several occasions (or DH if we had company ) but our dog was often outside (and I was in) and DH would just exploit me!

I have to say I still get a few odd ones that slip out inappropriately and I have to pretend cough to try to cover them up. I think my butt muscles copped as much of a hiding as my pelvic floor!
