Sensitive Nipples

My nipples have been hurting sooo much lately. When water hits them, it hurts. When it’s cold my nipples hurt. Rn just having a bra on is hurting. The slightest touch is hurting them. Idk what it could be. There’s no way it’s a sign of pregnancy as I’m a Virgin. Does anyone have any tips on how to deal with the pain or what is causing it? Pleaseeeee help. Thank you so much!
