I just got this off the internet:
Different Types of discharge
White: Thick, white discharge
is common at the beginning and end of your cycle. Normal white discharge
is not accompanied by itching. If itching is present, thick white discharge
can indicate a yeast infection.
Clear and stretchy: This is "fertile" mucous and means you are ovulating.
Clear and watery: This occurs at different times of your cycle and can be particularly heavy after exercising.
