Metformin & Clomid Success

Hi y’all! So I’ve been on 1500 mg of Metformin since August of this year for insulin resistance and PCOS. Trying for baby #2 and doctor prescribed 50 mg of Clomid to me to start off with. Has anyone had success with this? How many rounds did it take if you didn’t conceive on first try? Also, any twins!? Thanks.
