Tmi pic be warned

So I've had little leaks that I always thought were urine for a few weeks now. I heard that amniotic fluid was colorless. Well this is what I've been leaking and it looks more pinkish. Could this just be urine? Or watery pinkish discharge? Or what? I'm a little sketched out. My lower back is very sore today and I'm getting back spasms that aren't too often but one brought me to tears earlier. I'm 35w today. Any advice is appreciated

UPDATE: got tested, it was negative. But I have a bacterial infection... :/ yuck waiting for discharge and my antibiotic prescription order
