You need to see: a healthcare provider to make sure that you do not have some type of abnormality with your hormones. If you are of child bearing age or recently breastfed, then it may be a temporary condition where your female hormones are a little out of balance. But if the lactation persists, you will need some blood tests and examination to further diagnose any potentially serious problems.
