Mucus plug?

Tori • 21. Expecting my first little one July 5th! ❤️
  So last night I went poo and when I looked in the toilet after I flushed I saw what looked like it could have been my bloody show. I woke up around 3 or so with really a really intense cramp, but haven't had any since. I don't know if that was my mucus plug or just something weird in my poo. How long after you had your bloody show did you go into labor?
