Water bag or pee??!!!

Holly • Hi I'm 22 years old and pregnant with baby number three... Also girl number 3 so excited to meet my newest princess
I am 37 weeks with baby number 3... Been having contractions off and on for a while now but today they have been way more intense.. I went into the bathroom a little while ago and had a weird small gush of warm fluid randomly go down my leg... They stopped labor once already about a month ago... What could it be??!! I have Dr appointment at 9am
