Smelling better?

Does anyone have any tips on smelling better down there? Yes I clean, and I've never douched, ever. And I've just been tested for STD's and STI's about a week ago because of it, and I know I don't have a yeast infection because I've had a couple in my life. I eat healthy, I don't drink, I'm not on drugs, I just don't know what could be causing it. Everything just smells a little off in that area and I'm not sure why?

Anything would help!
