I’ve Had A Lot Of Vaginal Discharge Ever Since I

I’ve had a lot of vaginal discharge ever since I got my period at the age of 13, I’m 25 now and since then there is not a day where I do not have clean underwear. I’m tired of people telling me it’s normal. Sometimes it’s so much I feel like I’ve peed myself at times. I shower so much and wash with water every time I use the restroom, and change my underwear constantly. Im so embarrassed of it and I feel dirty. There’s no itchiness or redness or smells. I don’t know what wrong with me please help!
