Why did my period stopped and im only 15??

You should weigh 113 to 137 pounds. You in fact weigh 99 pounds. You are seriously underweight and are most likely anorexic. It is the lack of proper nutrition that is causing your problems.

Please check out the three links below. They are from my Group and provide information concerning anorexia both first from an anorexic’s point of view then from sites with appropriate information plus information on bulimia:

its stopped because your dangerously underweight if your too skinny your body will stop your period because it needs to concentrate on you putting on fat you can end up damaging your fertility if you don’t gain weight back soon and no, it wont come back until you gain more weight and become healthier talk to your doctor about it and get him/her to calculate your bmi (body mass index) for your height and age he/she will tell you what weight range your in and how much you need to gain to be in a healthy weight range and again, once you gain weight and become healthier your period will come back

She is right you are underweight sort it soon or you may damage you chance of having kids in the future

it may be that you are too thin. but I would suggest going to the doctor, they will let you know whats going on

go see the doc.
