People with PCOS

So I was just diagnosed with PCOS today, but I only have the hormone imbalance part of it. The only hormone that is high for me is testosterone. My free testosterone was 13.9 and my total testosterone level was 81. My doctor put me on Metformin HCL 500mg 2 times a day. I’m wondering if anything else helps lower testosterone levels? Any specific diets that help? I’m definitely new to this and never in my life thought I’d ever have PCOS so I’m definitely feeling defeated today. I do have a 3 year old, but I’m nervous this is gonna make it way harder to get pregnant again. Any advice is welcomed please.
