haha I have to say I am little confused now because I thought a "show" and the plug were the same thing???

'Plug' is a big glob of jelly like snot, and can be clear or have a streak or clots (my favourite word lol) of blood.

A 'bloody show' is a streak of blood in mucous or just a little blood in your undies or on the toilet paper - the blood is a sign that your cervix is dilating.

HTH smile
