TMI could this be my bloody show

So for the past 24 hours Ive been experiencing this kind of discharge when I use the bathroom and even a little bit in my underwear it started out pink like the picture below and now it's gotten darker like the first picture. I'm 36 weeks and 4 days pregnant with my first child so this is all very new to me. I've already talked to my doctor and she said as long as I'm feeling my baby move regularly, I don't start having regular contractions, and it doesn't get heavy like a period I don't need to go into the hospital and that I can just wait to see her at my next appointment. My next doctors appointment is on Thursday. Last Thursday was my last appointment and then I wasn't dilated or anything like that. So at this moment I'm left scratching my head wondering what if this is a sign, or what this really is.
