Very tender breasts for 6 weeks *not pregnant*

anon

Hi ladies so my BBs have been extremely sore for 6 weeks, no clue why. And I mean it feels like I'm getting shot in the boob. It started a few days after my ovulation last cycle, leading up to my period. They hurt during my period, and after, leading up to my next ovulation. They're very swollen and seem to be growing. I did a breast exam on myself and I only feel the 1 lump that's always there, but they feel very swollen in each breast. I went ahead and took a pregnancy test this morning just because weird things can happen like that. But it was negative as I expected it would be. They hurt with simple things like walking, bending over, moving around. Anyone know what this could be? 😕
