Hi,
How are you? It is good that your thyroid tests were normal. Irregular menstruation may be caused by hormonal changes, stress, too much exercise,use of pills or certain medications, infection, stress, change in diet or exercise routine, recent weight loss or weight gain,and other gynecological issues. If it persists, have this checked by your doctor for proper management. Your medical history and complete physical and pelvic examination will also help with the diagnosis. Do keep us posted. Take care and best regards.
