If your husband is "fixed," the chances of pregnancy is very low. Then again, it is still possible. Go to the doctors to be sure. Otherwise, you might have an overproductive production of a hormone called prolactin, which causes spontaneous secretion of milk from the breasts. If this is the case, you would also be missing your period. Make an appointment with the endocrinologist if it is shown that you are, in fact, not pregnant.
