Do women reveal private information to “friends”?

She told me she was not ready for a relationship and wanted to be friends. So flash forward us hardly talking she randomly texts me thanking me for something i got her and how it is helping her with her menstrual cramps. Do women just tell guy friends about their menstrual cramps like that? Or why would she reveal such information?
