Discharge?

Okay I thought maybe my water was leaking cause since yesterday every time I checked my panties they were wet... And then this morning I had some like slimy yellow green discharge, and now I've been having contractions every 20-30 minute and when I looked now on my panty linear It's a pinkish super light brown mix color.. More on pink side.. I'm suppose to be induced on Wednesday... When I smelled the wetness it has no odor... Should I go get checked? I was 2cm dilated on Thursday when I got checked  baby was still high but cervix was thinn.. Help?????
