TMI question!!

So for a couple of weeks now, I've noticed that my discharge has gone from normal color and texture, to green and thick. No odor, no itch, no burn, no hurt whatsoever.

But, I'm having to take extra vitamins besides Prenatal because I'm on prescription medication (I'm high risk, btw). Could it be taking all of these vitamins at once changing the color and texture? Or could it be more serious than that?

Any opinions and tips welcome!
