It is possible for discharge to occur at the nipples on pressing during and after ovulation,i.e., the luteal phase. Any discharge that occurs at the nipple spontaneously needs further investigation. Bloody discharge or discharge only from one nipple needs immediate attention. Pregnancy
can also lead to nipple discharge
even in the early stage. I advice you to consult your doctor and plan further management. Most of the nipple discharges subside spontaneously. Take care.
