Boob hurts so bad!!

So tender and swollen breasts are normal in pregnancy, I understand that. But they don’t hurt like that. But my left boob is being a pain in the ass. On the left side and towards my armpit is a pain. It doesn’t hurt to the touch but it’s becoming more and more painful. It happens one day and it’s gone the next. Idk how to explain it :( is it normal ?
