Vaginal discharge is the leucorrhea that is discharged from the vagina. The leucorrhea is the secretion of vaginal mucous membrane exudate, including the glandular ducts and cervical ducts of the cervix, and is subject to estrogenic changes in the body. The amount of vaginal discharge varies from time to time, but at the end of the menstrual period, the amount is small and it is sticky or milky and transparent. At the time of ovulation, due to the constant increase of estrogen in the body, there may be streaky leucorrhea that lasts for 2-3 days and will slowly subside. As you enter the luteal phase, progesterone may be more prevalent at this time, causing more shedding cells and making the vaginal discharge sticky and milky or yellow. It is important to wash your vulva every day, regardless of the period, and to pay attention to the hygiene of your vulva to avoid cross-infection and vaginal inflammation.
