Vaginal discharge 😬

So I’m 16 and I became sexually active when I was 14 (I’ve only been with 1 guy)every since I could remember I’ve had this thick white discharge (it goes away and come back) I went to see my gyn a couple months ago and she told me that it’s normal for a girl my age to have vaginal discharge 🤷🏽‍♀️ she even ran labs and they can back negative 🤷🏽‍♀️ has anyone else ever had this problem if so please comment it’s very annoying 🙃
