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.

Hello. This happens sometimes. Usually any sort of activity keeps the vata dosha exited. In your case, it is the one which is deranged. In Ayurveda terminology we call it avarana. Also check your hb levels. In case of reduced hb levels, periods gets delayed. Use trikatu churna added with ajwain powder, mixed with melted ghee before food twice daily and dosage each time being 1 tsp. Followed by lukewarm water sipping. Do this regularly for 3 months.
