Hello,, Progesterone production peaks in the week before you get your period(around day 21 in a 28-day cycle), which can cause expansion of the milk duct and lead to pre-menstrual breast tenderness. This is known as a "cyclical" form of breast pain, meaning that it occurs on a regular schedule. So don't worry. Only when pain is troubles your daily routine activities then consult gynecologist.
