Seek consultation : The most common reason for irregular periods is ovulatory dysfunction, which may be due to a variety of conditions - pcos, hypothalamic amenorrhea, thyroid disorder, hyperprolacitnemia, perimenopause or poor ovarian reserve, hyperandrogenism, etc. An evaluation therefore is the most important first step as the management of irregular menses and conceiving depends on the etiology.
