When you experiencing excessive discharges, it is a good idea to first rule out the possibility of an infection. I think that you did a good job of trying some self-care products for clearing a possible common infection like BV.
An infection-related excessive vaginal discharge often has a color, like gray, yellow, green or brown or a pungent odor, most commonly a fishy odor for BV. If an excessive discharge has no color (clear or white), nor odor, it might not be an infection. Non-infection related discharges can be caused by hormonal imbalance. An indication is irregular menstrual periods.
If you have visited a doctor's office and run a test for infection and the result comes back is negative for infection, and you have an irregular period, the likelihood is high that you might have a hormonal imbalance. We suggest that you see an OB/GYN specializing in endocrinology and run a test for your hormonal levels.
Get a clear diagnosis is important before seeking advanced treatment.
