What does it mean if you've had a miscarriage or an abortion in the past two years and your breasts still leak?

Not uncommon: Any pregnancy can stimulate the breast glands that make milk, and that can last quite some time after the pregnancy ends. However after 2 years usually the milky discharge would end. If it breast discharge is not milky you should be checked by a gynecologist or breast surgeon. Testing your prolactin level and thyroid function may indicate a hormonal problem causing this also.
