Vaginal infection with increased vaginal discharge abnormally, green color, bad smell after sex?

Ask
Hello doctor. I am 25 years old this year, I have had sex, every time I have sex during my period or a few days after my period, I have vaginal discharge for about 5-6 days, the first 1-2 days is small, the next days more and more already. Discharge in the first days is cloudy, slightly smelly, then gradually becomes greener with a bad smell. The doctor told me to ask if the discharge is abnormally increased, green, has a bad smell after sex, is it a vaginitis? How is the treatment? I hope you can give me some advice, thanks.
Anonymous question
Answer
Hello. Normal discharge is white like egg white or may be slightly yellow, has no odor or slight fishy smell, does not cause itching. The quantity and nature of physiological discharge varies depending on the age, stage of the menstrual cycle as well as the special times of a woman.
In the period before and after ovulation, the discharge is usually less and not persistent. In the middle of the menstrual cycle, 12-24 hours before ovulation, the body's estrogen levels increase, the secretions are abundant, so women feel wet and uncomfortable at their doors. According to your description, the discharge has a bad smell, an abnormal increase in discharge after sex during and after the menstrual period is most likely a manifestation of a gynecological infection.
You should go to a gynecologist at a reputable medical facility or one of the Vinmec Health System hospitals nationwide so that the doctors can confirm the diagnosis of abnormal, blue, and smelly discharge. Does bad breath after sex mean vaginitis and is there a treatment that's right for you?
