I don't imagine the normal flora of our vaginas vanish upon the appearance of menstrual blood. Even if there's not as much of it (which I'm not sure of, but perhaps there's less in the heaviest days since they are constantly being flushed out, but *shrug*) if you bleed through your underwear enough it should stain your pants as well.
When you're not on your period, does normal secretion ever soak through your underwear a little? It's happened to me and stained the inner crotch of my pants on the inside.
