TMI strange chunky discharge?

I have been experiencing this excessive, chunky whiteish/yellow vaginal discharge for just over a month now. I have been to the doctors multiple times, had tests for yeast, BV, every STI, pregnancy and all my tests are negative. My GP says there’s nothing more she can do for me! It’s so embarrassing I have never experienced discharge like this before my discharge is normally clear and watery throughout my cycle. Has anyone else experienced this before? Should I push to see a gynecologist?
