How many day before period usually breast pain begins?

Breast pain, or mastalgia, often begins about one to two weeks before menstruation, coinciding with the luteal phase of the menstrual cycle. This pain can vary in intensity and duration among individuals. Hormonal fluctuations, particularly changes in estrogen and progesterone levels, are typically responsible for this discomfort. If breast pain is severe or persistent, it's advisable to consult a healthcare professional.
