Generally speaking, breast pain may occur during the ovulation period, but this varies from person to person. However, having breast pain does not necessarily mean ovulation is occurring. If breast pain occurs during ovulation, it could be due to ovulation, but other conditions such as hormonal influences, breast hyperplasia, or mastitis cannot be ruled out. It is recommended that patients visit a hospital for examinations such as breast ultrasound or mammography to rule out any medical conditions.
