Nipple Pain Before Period: Causes and What to Expect

Nipple soreness is a common PMS symptom caused by hormonal changes (rising estrogen/progesterone before ovulation). PMS symptoms also include acne, bloating, breast tenderness, mood changes, cramping, fatigue, headaches.

Nipple soreness also occurs in early pregnancy but isn't a reliable sign. If unsure, take a pregnancy test. See a doctor if nipple soreness is severe or unrelated to menstrual cycle/pregnancy.
