Yeast Infection

Hello, my gynecologist recently told me that I had a yeast infection and honestly i never even noticed it... I’m not sure what I should be looking for in terms of knowing if I have one or not. My discharge was white n creamy but it’s always been like that so have i always had a yeast infection?? this is all too confusing to me. What should my discharge look like ?? cause to me mine looks “ normal” aka idk what is normal but my discharge looks like it has been all my life. I’d appreciate the responses!
