Hello, my name is Dr.Dorina Gurabardhi. I understand your concern. There are many reasons that cause delyed periods . It can be caused by : -Excessive weight loss or gain. -Eating disorders, such as anorexia or bulimia. -Increased exercise. Missed periods are common in endurance athletes. -Emotional stress. -Illness. -Travel. -Hormone problems. This may cause a change in the levels of the hormones that the body needs to support menstruation. -Problems with the pelvic organs camera.gif, such as imperforate hymen, polycystic ovary syndrome, or Asherman s syndrome. So you should do some examinations to find the cause of yourine symptoms. I suggest you an xray and a visit to a gynecologist .Hope my answer was helpful, if you have any other questions I ll be glad to help, thanks!
