"Bloody show' is a term for losing the mucus plug bc it is often tinged with a little blood.
As for when you'll lose it, it varies. Some women lose part only to have it regenerate and then lose it again later on. Some lose bits and pieces throughout the pregnancy. Some lose it right before labor. Or you could be like me and lose it after 25 hours of labor and you're just about to start pushing.
It's really a guessing game.
