39 weeks: Small gush of fluid with brownish looking blood?

Christie
I am 39 weeks tomorrow and had a tiny bit of brown blood on my underwear last night.  I had very irregular contractions throughout the day and then a small gush of liquid tonight that went through to my pants (but not mucous) like with more brown.  Could my water have broken and should I be worried about the color?  Thanks for the help- nervous FTM
