28 weeks pregnant took monistat yeast infection test stick didn't change color uncomfortable itching no odor is monistat 7 safe to use?

Yes, it's safe.: The Monistat test kit measures vaginal acidity to screen for a bacterial vaginal infection. If the color DIDN'T change, then it's more likely that your symptoms are caused by a yeast infection. Re-read the instructions to confirm that. The test is accurate in measuring acidity but not particularly reliable in determining what's causing your symptoms. Still, Monistat 7 is safe @ 28 weeks.
