my period isn't for another 10 days ! why is my breast extremely soar ???

Like extremely soar ! I can't even wear a bra and my husband can't even touch my breast from how soar it is usually its soar one day before period day or on period day .. I been ttc for so long that I honestly lost hope that it's pregnancy symptoms but if so has anyone ever been pregnant and felt this way a few days before like 10 days before also and been Prego? Very curious
