Some causes of normal nipple discharge include:
- Pregnancy. In the early stages of pregnancy, some women notice clear breast discharge coming from their nipples. In the later stages of pregnancy, this discharge may take on a watery, milky appearance.
- Stopping breastfeeding. Even after you have stopped nursing your baby, you may notice that a milk-like breast discharge persists for a while.
- Stimulation. Nipples may secrete fluid when they are stimulated or squeezed. Normal nipple discharge may also occur when your nipples are repeatedly chafed by your bra or during vigorous physical exercise, such as jogging.
