Hi!
If you were my patient, I would advise you that the next step for you may be Clomid or Femara. The Metformin may regulate your cycles by itself, or you may need some medications to help boost ovulation--such as the ones above. IF you start having regular periods you will want to check ovulation predictors and a progesterone level to confirm that you are indeed ovulating--You must ovulate to conceive.
Good luck!
