PCOS diet

Hi, I have been diagnosed with PCOS since I was a teenager. My husband and I have been ttc for 3 years now and I was put on Metformin but I was sick the whole time I was on it so my doctor took me off. My previous doctor passed away and the new doctor that took over refuses to help me until I lose weight. Which I do get in a sense. Yes I drink soda and do eat out a couple times a month but I have agreed to stop those completely. I’ve been re searching diets and can’t find a PCOS diet. So my question is there a certain diet you followed to help with PCOS? Or tell me what you followed food/vitamin wise in order to conceive I would really appreciate it :)

Thank you!
