For women who have breast fed previously, there may still be some colostrum leaking out even months after they have discontinued breast feeding. Pregnant women typically do not see any colostrom until the last trimester.
You may be thinking at this point "but I've never been pregnant or breast fed prior to this leaking". This leaking can occur at any time, pregnant or not, history of breast feeding or not.
During your normal monthly breast self exams, you will see some discharge when you squeeze the nipple. If you start seeing any discharge that occurs without this exam, and have the following, please consult your doctor right away:
* Leaking without squeezing
* Leaking that occurs often (for those who are not currently breast feeding)
* Leaking from one nipple more than the other, or just that one alone.
* If the discharge contains any tint of pink or red indicating blood.
* If it is clear or solid white in colour
* If it appears like egg whites
There may be another cause for those women who see leaking from both nipples. These women have what is known as "galactorrhea". They have a harmless, tiny tumor in the brain that triggers a response for more milk producing hormones called prolactin. This tumor (or even tumors) do not require surgery to remove.
Always discuss any concerns you may have with your doctor. Tell him or her your symptoms, ask for a breast exam or mammogram if necessary. Let your doctor know if you are on any medications prescribed by other physicians. Some medications cause this, so read the pharmacy labels carefully.
I'd wait to test in another day or two and see if AF comes...if no AF and a bfn, I'd call your doctor...I don't know very much about this other than the fact that I had a friend who had this problem (it wasn't milk just some discharge-like stuff) that turned out to be caused by a hormonal problem and edometriosis.

Normal vs. Abnormal
As a general rule of thumb, the only time when fluid should be leaking from a breast is during pregnancy and breast-feeding. When it happens any other time, it is best to get the breast or breasts examined by a physician just to be sure that there isn't some underlying health problem that needs to be addressed.
Leakage from Both Breasts
If fluid is leaking from both breasts, chances are good that a hidden condition is affecting the whole body in a systemic way. This may be an endocrine problem. Another possibility is that some sort of medication could be the culprit. Many different kinds of your garden-variety prescription drugs, including Prozac and birth control pills, are known to mess with the breasts. When both breasts leak, it might be a good idea to pay attention to any other symptoms that may seem unrelated, as they may all be caused by the same thing.
Leakage from One Breast
When the fluid comes from just one breast, it is much more likely that the cause is localized to just that breast. Discharge from the nipple may be a sign of any one of numerous problems ranging from breast trauma to cancer.
Get it checked out!
No matter what the case, it is very important to have these symptoms checked out by a doctor so that any potential illness or condition can be treated quickly and effectively. The doctor will ask questions about medications you are taking, other symptoms that go along with the various hormonal disruptions, and recent experiences. She will also examine both breasts and look at the color and consistency of the discharge. Tests will be ordered, if indicated by the in-office evaluation. These might include blood tests, lab tests of the discharge, or even a mammogram.
