For the last few days my breasts have been hurting pretty much just on the bottom. it started off as just my nipples now it's the actual breasts. my period isn't due for another 2 weeks so i'm just wondering why.

Breast pain: Pain in both breasts together is nearly always from benign hormonal fluctuations, more commonly in young women. Knowing your age would be helpful here. Sometimes pressure from an improperly-fitting bra can cause similar symptoms, as can running/sports. Redness of the skin, nipple discharge, or a painful lump or mass that you can feel would be cause for concern and evaluation in-person.
