Anyone used monistat testing kit?

Bought this today, told me that if the tip of the test turns green or blue, I need to see my doctor and that my vaginal pH is off. 
If the color of it doesn't change, my pH is normal but I could have a yeast infection if I have the symptoms... So I did both the tests and they didn't change color so I assume I have a yeast infection. My symptoms are the itchiness, soreness, and swelling/pain during sex... But I don't have any discharge that looks white and chunky like people say. Can it still be a yeast infection if my discharge looks okay? And I don't have any weird vaginal odor or smelly discharge either, which is another symptom of yeast.
