First time mom.... getting really worried

Crystal
Okay, I need some advice here. I am 37 weeks pregnant.  I have been contracting for about 3 days now. Went to the doctor on day one, told her my symptoms(cramping, lower back pain, passing slightly bloody, thick mucusy discharge) she thenchecked to see if I was dialated and I was not. She then tells me that this could go on for days, even weeks and tells me to "take it easy"(but doesn't insist I take off work just yet) Fastforward to today, I am still passing a little bit of that mucusy discharge but now my contractions seem stronger and more frequent. All day today I have been "leaking" clear fluid that doesn't really have a smell. Not gushing but enough to soak a panty liner. I don't believe it to be urine because my urine is slightly yellow from my prenatal vitamin......what should I do?
