Mucus plug?

Woke up to my pants SOAKED with liquid and then this??? I’ve been having contractions all weekend around 5-7 and 7-10 mins apart. I’m confused as heck right now! 40w today!!

Ps I wiped 3 times and every time it had a string of pink in it. Last night went to the bathroom and it had a brownish red streak or string in it.
