🔹 What Causes Breast Pain Before a Period?
The main cause of breast pain before menstruation is hormonal changes. As the body prepares for a new cycle, estrogen and progesterone levels rise and fall. This fluctuation can make breast tissue swell, leading to tenderness, heaviness, or aching sensations.
-
Prolactin, a hormone that stimulates milk production after childbirth, can also affect non-pregnant women. Changes in prolactin levels sometimes contribute to breast discomfort.
-
Some women notice breast pain during ovulation (around days 12–14 of the cycle), when the ovary releases an egg.
