Breasts too sore

Izabella

I may or may not get my period soon because the last time I had sex, it was unprotected. But my main concern are how sore my breasts are. My boobs have been a little more sore than usual before my period and I also noticed they feel a little lumpy on the sides and are extremely tender. Should I worry? Should I go to my doctor and get them checked out or is this normal?
