Advice please PCOS

Hello, I have PCOS I’m 25, 5’1” and 167lbs. I’m taking Metformin 1,500 mg each day, and drinking Ovastol twice a day. Along with some extra vitamins I need. My fertility doctor wants me on a Mediterranean diet. But I am a very picky eater. There’s not a whole lot I will eat. What items should I cut out of diet? What things would you consider as bad carbs? What would you replace as a snack, meals? Trying to help my PCOS so I can get pregnant. If you have any ideas, things that helped you. Please put them down. I have had 5+ years of negative pregnancy test. And just found out I have PCOS in January 2024. Thank you!!!
