I'm 31 and it's never happened before. I know for sure I'm not pregnant. I have relocated to a different country for work. I have lived in said country before for 3 years and never had this issue. However, this new company and city have been extremely difficult to deal with. I was thinking maybe it's stress related, but I have been through many levels of stress in my life and this hasn't happened before. I have also had severe fatigue, insomnia, and brain fog. I recently had an ultrasound of my uterus in November and everything was great, so I don't believe it's menopause or cancer related. Does anyone have any idea how I can get my period back?
