Pcos and Pregnancy

My husband and I about a year ago found out I have pcos we have been trying for a baby for almost 2 years now I took metformin for only a month because it made me so sick I couldn’t get out of bed everyday. I now in the last 5months have started getting a regular monthly period and miscarried a few months ago at just 6weeks along. What can I do to have a successful pregnancy? My doctor is completely useless in the matter and I’m all on my own until I find a better doctor. Any advice would be great because I’m at an all time low feeling like we will never have a family of our own 💔
