When can i expect to ovulate on metformin? will be a mnth on metform 3/12/14.

No guarantee: Metformin helps women with polycystic ovarian syndrome and Insulin resistance. By decreasing Insulin resistance it helps to regulate periods, and can help with ovulation, but the efficacy varies from person to person. Sometimes it works rapidly (within one month), but other times can take months to work, or may not work well enough alone, so that you require other treatment.
