Peachy color???

So I'm 37+4 and was 3cm 10-20% effaced Friday... but have been having strong bouts of contractions and pressure that has clearly been working my cervix (I can feel the changes). Well I went for a long walk in hopes to keep things moving. I came back had to pee of course, all was fine... then had contractions and pain hit very extreme down there.... 30 mins later I used the bathroom again it was a light peachy color... could I be leaking my water or bloody plug??? Possibly a UTI late in the game???
