PCOS diet

Hello all! So I recently was diagnosed with PCOS. My NP put me on Letrozole and I officially didn’t ovulate this month again😑 I’ve been listening to this podcast called the PCOS nutritionist and a lot of what she is saying makes sense with the symptoms I have. I’m just wondering if anyone else has treated their PCOS just with lifestyle changes (diet/exercise). I will continue to try Letrozole because I know it sometimes takes a few rounds. Just curious if this is all bs or if someone had had success getting pregnant? Let a girl know!! 😊
