leak or discharge?

I'm 37 weeks and been feeling crampy and have contractions off and on any who when I go to the bathroom I have a white water looking discharge that smells like semen (sex is not a option for me) at times it comes out more watery then others. Also it dont happen eveytime but happens frequent .Anyone have any idea what this may be
