Possibly in labor?

Catie

I’ve had period cramp like contractions since last night around 10, today around noon I lost my mucus plug again which had some blood in it, then around 2 (tmi) I had some diarrhea, now my contractions for the last hour have been around 4 1/2 minutes apart lasting 1 minute. Should I wait longer to see if they go away or head in?
