Lately I've been experiencing more vaginal discharge than usual, and it is very watery (to the point that throughout the day I feel like I'm "leaking," and if I'm in a towel after a shower it will drip down my leg). More recently I noticed that the discharge had a yellowish-green color to it as opposed to the cloudy white it had been. Besides being particularly thin/liquidy and an unusual color, there is nothing remarkable about it; it has virtually no odor and it is not accompanied by any itching, burning, pain, redness, etc. I'm 21 years old, not pregnant, and have not tested positive for any STDs. Anyone have thoughts as to what could cause the changes?
*I plan on scheduling an appointment with my gynecologist to be safe, just looking for any insight you all might have in the meantime
