Mucus plug?

Danielle • 👼🏼💙🤱🏼💙👼

I’ve slowly had a little bit of stretchy greenish yellow sometimes clear come out when I wipe it’s happened about once a day. Is it possibly my mucus plug slowly shedding? I’m currently 36 weeks with my rainbow. Also when you do slowly shed your mucus plug does that mean you’re at least 1cm dialated?
