Google "galactorrhea" or inappropriate lactation. I'd consult a doctor about it.
Hi there and welcome. Well, it IS time to consult the doctor. I would make an appointment promptly. Some women have prolactemia which is lactation when there is no baby. It can be due to hormonal imbalances such as producing too much estrogen or due to a small, harmless tumor in the pituitary gland. But usually it is both breasts when that is the case. It could be an infection. Or something more serious. So, you need to be seen by your doctor as soon as possible. good luck
