Girl, I completely understand. It pisses me off how little medical attention/knowledge there is on PCOS, I'm sure if there were internal cysts in men's testosterone that caused them to produce abnormal amounts of estrogen they would've be on that ASAP. And yes! Nobody ever bothered trying to diagnose my problems (even though I had trouble with my periods ever since I was 12) because I was thin and people think PCOS is a weight related problem. Oooh interesting, it actually seems that BO is helpful towards PCOS maybe because it raises progesterone? Glad you were able to find a natural remedy to help you out.
And I'm on a low carb diet as well, not to the point of keto because I'm an athlete and my run gets drastically slower on a keto diet unfortunately
