Hello and I hope I can answer your question. There are many reasons that can make a woman miss a period. Stress, sudden changes in weight, traveling to different time zones, all can alter a woman s menstrual cycle. Other medical problems like thyroid disease or other hormone imbalances can make you miss a period. When you miss your period, the hormones build up so you feel more hormonal until you finally menstruate. I would recommend you consult with a GYN doctor for this condition. They can check your hormone levels to find out what caused you to miss your period for so long, and give you medication to make you get your period again. I hope you feel better soon and that I answered your question adequately. Best wishes, Dr. Brown
