Hello...... Breast tightness is due to harmonal variation.... This is exepcted with the rise of progesterone.. Breast tightness, nauseating feeling, mood swing, irritability etc.. are the symptoms of premenstrual syndrome.. But you are having this problem since 1 week, you have missed period, consult gynaecologist........
