Hi, Thanks for the query. Poly cystic ovary disease presents with irregular periods, anovulation, insulin resistance etc. Metformin helps in treating the insulin resistance. The possibility of pregnancy depends on whether ovulation is occurring or not. As you are having irregular periods, it is difficult to guess the period of ovulation. So, after getting your periods, track the ovulation either by kit or by physiological methods.

If needed you can take tablets to induce withdrawal bleeding and for ovulation induction with your doctor s advice. Take care.
