I Am 35 Weeks Pregnant And I Have Discharged Twice

I am 35 weeks pregnant and I have discharged twice that was hard rubbish snot like discharge and tonight I had discharge that was snot like again but more string like or like gewy, does that mean I am losing my mucus plug? at my last doctor visit i was over 50% en-fazed, and I am having server cramps and pressure that is so much that I feel a lot of pressure in my vigina..does that mean labor is on its way?
