Hello,

The doctor may prescribe metformin, an insulin-lowering oral drug for type 2 diabetes, which can help ensure ovulation and regular periods.Metformin can enhance ovulation and regulate menstrual cycles.

This means if you are sexually active, you should use birth control to prevent pregnancy, even if you haven't been getting your period regularly. Metformin may even improve cholesterol and hirsutism symptoms like acne and excess hair growth
