Weird discharge

Hey ladies. Soooo I'm having some slightly weird discharge. It's slightly greenish, no odor... No itch... No irritation. I've been taking some different supplements but I don’t know if that can cause it. I've had bacterial vaginosis multiple times before but always had a smell. I've had yeast infections before so I know this isn't that. About a week or two ago, I started feeling like I had a uti. Took an AZO uti test and the leukocytes turned purple after about ten to fifteen minutes. I felt pressure in my lower abdomen and the needs to pee often, but not burning or pain when I actually peed. After a few days the discomfort went away... But now I'm seeing the discharge. and I've had some discomfort in my lower right back (not up where the kidneys are). Any ideas?
