A vaginal discharge can result from normal changes in estrogen levels. When levels are high, estrogen stimulates the cervix to produce secretions (mucus), and a small amount of mucus may be discharged from the vagina. Estrogen levels are high in the following situations:
- During menstrual cycles a few days before the egg is released
- In newborns for a week or two after birth because they absorb estrogen from their mother before birth
- A few months before girls have their first menstrual period
- During pregnancy
- In women who take drugs that contain estrogen or that increase estrogen production (such as some fertility drugs)
Pregnancy, use of birth control pills (oral contraceptives), and sexual arousal also affect the amount and appearance of the discharge. After menopause, estrogen levels decrease, often reducing the amount of normal discharge.
