Mucus plug.

Ally

I know it’s normal to lose part of your mucus plug & have it grow back. But I’ve been losing bits and pieces of it for like the last two weeks. No blood. So I’m not too concerned. But can anyone tell me why this happens? Or what it means. Everything I’m reading online says that I’m close to labor. But I don’t think that’s completely accurate. I’m due September 4th. But measuring a couple weeks ahead.
