I’m 16 and have now missed 2 periods. The end of my last period was 88 days ago. I’m 100% not pregnant. I got my Period a year and a half ago. Should I be concerned?? There has been ALOT of stress lately and possibly poor diet. What can I do? PLEASE HELP I’m freaking out. I’m experiencing back pain, bloating and hormonal breakout but I have for the last week and nothing!!
