You are unlikely to be pregnant if your pregnancy test was negative, especially if you keep getting your periods. Milk production does not usually occur until later in pregnancy. If milk came out of your breast, there are other possible causes.
Simply stimulating the breast can cause a milky discharge in some women. Another cause is nipple stimulation, especially during prolonged foreplay. Oral contraception is yet another possible cause, as are antidepressants and antihypertensive drugs.
Hyperprolactinaemia is the presence of abnormally high levels of prolactin the blood of women who are not pregnant, and in men. Prolactin is a hormone primarily associated with lactation (the secretion of milk from the mammary glands). The condition of your breasts producing milk when you are not pregnant is called galactorrhea.
Hyperprolactinaemia is relatively common. The causes include certain medications, stress, thyroid problems, kidney or liver failure, and even certain herbs. It is diagnosed by a blood test. This may be the reason that milk came out of your breast. The treatment depends on the cause but is most commonly by medication, such as Parlodel (bromocriptine) or Dostinex (cabergoline).
A condition called duct ectasia can cause a milky discharge from the nipple, especially in older, premenopausal women. It is often the result of inflammation due to hormonal changes. It is a condition in which there is dilation of the lactiferous ducts, which lead from the lobules of the mammary gland to the tip of the nipple. Smokers are thought to be more susceptible to duct ectasia.
If you are concerned, consult your doctor. He/she will be able to make a professional diagnosis and identify any underlying problem.
