PCOS best supplements

So I’m so lost again and I don’t know what to do, I’ve been taking dim since 2023 i completely stopped getting hormonal acne and I was getting my period clockwork every 28 days, but this year I decided to reduce the dose to 100mg (I was taking 250mg) because I’ve heard it’s not good to take it long term I think it can mess with your thyroid and lower your estrogen. Well I think my periods are even more irregular now, some months I get my period late, other months I’m getting my period twice and I don’t know what to do anymore. My acne has also returned but I don’t want to keep taking dim because I don’t know if it’s safe to take it long term. I’ve been thinking of trying saw palmetto or inositol (again even though I took it twice and I didn’t notice it helped to regulate my period or helped my acne)
