Scared.

Im 20 weeks & 3 days, i just went to the restroom and when i wiped 2 blobs of what i thought was the mucus plug was on the tissue. There was no blood, pink, or brown. Im not sure if its just thick discharge. I dont know if im just scaring myself or over thinking this all. I wish i would have taken a picture. What should i do??!! When you start losing you mucus plug does it mean your going into labor?
