Hard to say for sure if its too late. But it's not going to fix itself, it may only get worse if left untreated. If I were you I would run nolva at 40mg ED until it clears up. It my take 6-8 weeks, even longer.
And I don't know what kessar is. The only two compounds I know of for treatment of gyno are Nolvadex and Raloxifene.
