Cyclic breast pain appears to have a strong link to hormones and your menstrual cycle. Cyclic breast pain often decreases or disappears with pregnancy or menopause...scanty periods has many possible causes...it can occur in women who have diabetes or thyroid problems. It is also common in women with high levels of a protein called prolactin in their blood...it can be the side effects of certain drugs like oral contraceptives,antipsychotics,antiepileptics...it can be due to poly cystic ovarian disease as well... So I would suggest you to consult nearest gynecologists for detailed clinical examination and evaluation they will do the needful.
