Do breasts have to hurt ovulate?

Not necessarily. It is a common misconception that breast pain is a sign of ovulation. While it is true that some women experience breast tenderness during ovulation, it is not a universal symptom and many women do not experience breast pain at all during their menstrual cycle. There are many other signs of ovulation, such as changes in cervical mucus, changes in basal body temperature, and mittelschmerz (painful ovulation).
