Hurting nipples month after month

Dee
So I stopped BC pills in January and it seems like for most of the month my nipples hurt to the touch & are very sensitive. Anyone have any thoughts on this or experienced it?. And I've have 5 periods since Jan if that helps, 2 in jan 1 in feb and 2 in March. Nothing yet for April. And I would go see a doctor but I don't have insurance
