Most likely Bacterial vaginosis (BV)
Explanation:
BV is a sexually associated health problem in women caused by a change in the normal balance of bacteria in the vagina.
This happens when the population of the good bacteria called <em>lactobacillus</em> reduces, giving room for the multiplication and growth of bad bacteria. The good bacteria keep the vagina a bit acidic, thereby preventing the growth and multiplication of bad bacteria.
A woman that is sexually active is predisposed to having BV. White vaginal discharge that appears milky is one of the symptoms of BV. A vaginal pH 6 affirms it is mostly a BV, as the pH level that is greater than 4.5 would favors the population of bad bacteria.
