Yes but complex: Estrogen levels peak at mid cycle causing breast duct enlargement whereas Progesterone peaks just prior to menstruation and is associated with lobular growth. This will vary from one woman to another dan be related to family history, or caffeine or weight. If atypical for you consider pregnancy test. Birth control may help to ease.
