water breaking? one small gush then nothing

Beth
So I am 40w 5d and I just woke up after sleeping for about 5 hours like usual.  I shortly after felt a small gush of fluid from my vagina.  It felt rather like when your period starts so I know it wasn't urine.  The fluid was clear and slimy.  I was laying down when I felt it and when I stood up and walked to bathroom (twice) nothing more came out.  Anyone have this? Would you go to L&D?
Background: I had some very painful but far apart contractions before falling asleep tonight.  We also had intercourse.
