Lots of reasons: This could be from the changing hormone levels that occur during your menstrual cycle (very common). It could also be irritation from a bra you wore that day. It can also be irritation from a certain soap or even a skin infection. If you can't relate it directly to something irritating/menstruation, you should discuss it with your doctor.
