Cervical mucus or mucus plug

Andie • 28 with baby #2 on the way
How do you tell the difference? I went pee earlier and when I stood up in the bottom of the toilet was a big booger like blob in the bottom of the toilet and then just now when I wiped tons of mucus on the toilet paper. Im not having any cramping or bleeding and am only 23+5. Should I call the doctor now or can it wait til Monday since I'm not cramping?
