[/INST] Hi, Thanks for your question. I don't think the medicine you are on, or have had could have caused this period problem. You have not provided the details of your test results & from the medicine you are taking I have guessed that you may have an ovulation problem (since you are on metformin, are unable to conceive & have delayed periods). So, my suggestion for you is to register yourself at a good fertility clinic with your partner & get yourself fully evaluated. Once a cause is found you may be offered a specific treatment which may be ovulation induction in your case. Wish you best of luck </s>
