Hello there, Irregular periods are often related to sedentary lifestyle,irregular and unhealthy diet,lack of exercise and excessive exertion during normal periods. Also if you are overweight it should add up to your problem. Ayurveda considers it to be vata dushti I.e. The vata dosha in your body is not able to do its work properly . My suggestion will be see a experienced ayurveda PRACTIONER near you and get it treated in time before the symptoms aggravate.
