TMI QUESTION:

I had sneezed and like most pregnant mothers I peed myself a little but when I stood up and was walking towards the bathroom I could feel just a little leak and waddled as fast as I could and when I pulled my pants down I had this discharge stuff on my underwear. This is my 2nd child but I lost my mucus plug right before having him so is it possible to lose it or am I about to have this little girl today? Any advice is helpful.
