vaginapagina | Avoiding bloody sheets

So I've always wondered what other menstruating women do to avoid getting blood on their sheets/mattresses when they're sleeping. Personally, I'm a pad kind of girl, but man do they do an awful job when I'm sleeping! Ruined pj bottoms and suspiciously spotted sheets have taught me to sleep on a towel when I have or am expecting my period... but that's still a pain because a) I'm a picky sleeper and the towel is sometimes uncomfortable and b) I still end up with blood stains, just on my towels. I guess I should just invest in a really dark towel...

I'm mostly just curious what other women do - some of the girls here must have clever ways of dealing with this. :) Do you just sleep with a tampon in, or a menstrual cup? Hmmm.
