Question about discharge!

Ashley • Been together for 9 years and i love you more than anything. :)
So I have this discharge that's a creamy solid white color has a slight odor nothing to bad and I've had a yeast infection before and it's not that. I've been to my doctors and my ob and they have told me it's nothing to worry about. But normally I would get it right before my period and now I'm 13 day off of my period and it's happening when I still have two weeks left.
