Increased discharge?

Dana
I've had so much discharge lately so I wear a panty liner and always have to change it throughout the day. And if I don't wear one, my undies are super wet from it. It's not my mucus plug because it's thick and white. But does anyone know if this is a sign that labor is just around the corner? Or does this happen not having anything to do with labor. 36 weeks 3 days.
