How to deal with slight inflammation found in a routine vaginal discharge test?

Patient's question:

Age: 26
Doctor:
Hello! Two days ago, I went to the hospital for a routine vaginal discharge test, and there were no signs of yeast or trichomonas. Additionally, you can give your child some brown sugar ginger water, but it's recommended to use it occasionally. You can also give your child foods that help moisten the lungs, such as pears and lily bulbs. Later, I bought a box of Jinfukang brand Xiaomi Shuan (a box contains 5 pieces), but after use, there were always some white and brownish residues left in the vagina. I'm quite worried now—don't know if it's a fake medicine or a normal drug reaction. If it's a normal drug reaction, how many more boxes should I use?
If it's fake, what should I do? Will it affect my future ability to get pregnant?

Doctor's answer:

It's best to go to the hospital for a check-up to rule out the possibility of vaginitis. At the same time, a routine vaginal discharge test should be conducted to check for any signs of infection. Once the cause is identified, targeted treatment can be recommended. Married couples should be treated simultaneously.
Underwear and pants should be washed separately. If possible, disinfection should be performed. Clothes should be exposed to sunlight after washing. During treatment, sexual intercourse should be avoided to prevent cross-infection.
Suggestions: Maintain cleanliness and dryness of the external genital area. Avoid scratching, hot water washing, and using soap. When infected, use potassium permanganate solution for sitz baths. Underwear should be breathable and loose-fitting. Avoid alcohol and spicy or allergenic foods.
