TTC for a year

My husband and I have been trying for a baby for a year and a few months. I have been to my primary doctor multiple times and he’s trying to work with me researching and giving me tips. So far I have been put on a specific diet and I am taking Metformin. I haven’t been diagnosed with anything yet even though my paper work says he is treating me for PCOS. I know he’s working very hard to help us conceive but I think it’s time I need to be seen somewhere else. I feel like we are not getting anywhere at all. I have irregular periods but I do ovulate on my own. What is your advice for me?
