Do you have breast tenderness always after each period? If yes, it is normal. What is normal for you may be different for another person. If this always happens, then I would not worry, it is normal. However, if this is out of the norms for you, consult a doctor. However, a lot of women do get tender breasts after a period. In my case, I got soar breasts after a period and this was not normal. It turned out, I was pregnant. So, it could also be a symptom of pregnancy.
Good luck.
