Constant discharge

Hi guys! So I'm 22, been on birth control since 15 due to heavy periods. For as long as I can remember, I always had discharge between my periods. Like every day, CONSTANT discharge. So bad that I have to wear a liner pad everyday! Now this has been going on since I was like 13 and I'm getting so tired of it. I talked to my Gyno and we tried changing birth control, she ran test and I have no infections. She told me to try taking vaginal probiotics but nothing has changed! The discharge is clear/white. Does anyone else have the same problem? Or know how to make it stop!?!? Ya girl is tired of having to wear a pad everyday and I'm so conscious of it when I go on dates! Thanks yall!!
