Vaginal discharge is normal and varies during your menstrual cycle.
Before ovulation (the release of the egg), your body produces up to 30 times more mucous than it does after ovulation. The mucous is also more watery and elastic during that phase of your cycle. You may want to wear panty liners during that time.
A normal vaginal discharge consists of about a teaspoon (4 ml) a day that is white or transparent, thick to thin and odorless. This is formed by the normal bacteria and fluids the vaginal cells create. The discharge can be more noticeable at different times of the month depending on ovulation, menstrual flow, sexual activity and birth control.
