It's funny, when I first saw this thread yesterday, all I could think of was one of my pregnancy books that seems to really promote hysteria, and there's a passage basically saying that if your breasts become suddenly smaller you should panic and your baby has probably died. My doctor has been telling me all along to not read most of the popular pregnancy books, or at least to take their advice with a grain of salt, because they really do make you absolutely terrified of every single little thing -- and I'm so glad he has been hammering that into my head, because your body really does all sorts of sudden and strange things when you're pregnant and almost all of it is TOTALLY FINE. Weird and possibly disconcerting, but no reason to freak out and assume the worst. Damn those books!!!
