Am I close? Is this normal?

Nichelle

So I just lost what I think was my mucus plug. It was brown and slimy and about as long as my pinky, if not a little longer. But now I'm having yellowish diahhrea and prettty bad pelvic cramping like I have my period. Is all of this normal?? I was also just checked yesterday by my doctor. I'm 1cm and 50% effaced.
