Breast pain during ovulation may be caused by a variety of reasons. During ovulation, a woman's hormone levels change, which can affect the way her breasts and nipples feel. In addition, inflammation or infection of the breasts and nipples may also cause discomfort.

Some possible causes of chest pain during ovulation include:

1. Inflammation or infection of the breast and nipple, such as breast cancer or breast fibroma.

3. Pregnancy or changes in hormonal levels.

4. Other diseases or symptoms, such as depression or anxiety.
