PCOS?? High testosterone and natural treatments

I just got my blood work back from my amazing OB and I have high testosterone. I don't have excess hair, my periods are every 28 days, I have very little acne, if any and I am not insulin resistant. She's a little shocked by my high testosterone. However, my stress level is through the roof which in turn makes my cortisol levels increase which makes testosterone levels increase. She wants to perform an US day 14 next month to check my ovaries to rule out or confirm PCOS.

She's started me on Ashwaganda, fish oil, magnesium, DIM as well as a prenatal and wants me to start a Keto diet. I am not obese by any means but I can afford to lose a few pounds. Just curious if anyone has the same issues and takes the same natural supplements and if its been working for them 😊
