"Bloody show"?? What exactly is it?

Has anyone gotten it? Is it a sign that labor is near? What exactly should I look for? I went to the bathroom today and after wiping, noticed there was some spotting, wiped more and there was a bit more. Just a few drops about. Could this have been it?? I'm 39 weeks tomorrow 🙂. Can you ladies tell me your experiences with it? And how soon after did you go into labor?
