Just diagnosed with pcos but no treatment

Been TTC for 6.5years. Been on Clomid off and on for 5.5years. Have had 2 MC. Started Clomid again last month and had follice scan monday. The dr told me they were not large enough to go foward with iui and that i hace pcos and should be treated with Metformin and that he would talk to my normal obgyn as she was unable to do scan. Your a call from her office and didn't think treatment was necessary at this time. Anyone else hear that from their Dr?
