36+5 and have yet to lose mucus plug, anyone else?

I know it's not extremely important that I lose it or not. But if I lost it would that mean I have began dilating? I will be 37w Saturday and I just want some progress. Baby has dropped, and I have felt more period cramping, intense lower back pain and lightening crotch pains. It feels as if she is in my vagina! Anyone else as far along as I am? What are your symptoms?
