Here's a rough guide on vaginal discharge when you see such colors on the 'nasi'...
Clear and Milky
Cottage Cheesy White
White, cottage cheesy vaginal discharge can be a sign of a yeast infection. Yeast infections are simply an extra abundance of the yeast fungus. This condition is extremely common in women who are pregnant, have diabetes, or are on any type of antibiotics.
Grey Vaginal Discharge
Another condition of the vagina is bacterial vaginosis. This is detected by a gray vaginal discharge, itching, and a fishy smell. It is nothing to be worried about because it can easily be treated by taking antibiotics. Usually this is in the form of a pill.
Green or Yellow
A sign of a more serious condition called Trichomoniasis is a green or yellow vaginal discharge. This is also accompanied by a nasty odor. This disease can be caught from a sexual partner without using a condom. Unfortunately, women can have this condition for quite a while without knowing. Many times, a characteristic of the vaginal discharge associated with Trichomoniasis is a bubbly quality.
