My water or discharge??

So here’s the situation. Im 36 weeks pregnant and the past few days I have been having A LOT of thick yellow kind of greenish discharge. It doesn’t smell and I’m not having any significant itching or burning but still just figured it was a yeast infection or something. I decided to wait until my doctors appointment tomorrow to ask if they could check for an infection. Well today while i was at work I felt a small gush of water and then slight trickling in my pants. It’s alarming me because I had to pee but it felt distinctly like when you have a period and the blood gushes from your vagina. When i was finally able to look my panties were pretty wet but I had a bunch of the discharge and it looks more green than usual. Would this be my water or is it something else? I have work in a few hours and I’m not having any contractions so I’m really debating on if I should go tonight or just wait for my doctors appointment tomorrow morning
