Irregular periods, it's been 83 days since my last period

Hello gracce

Here is info for you -

One of the common reasons for girls to stop having their periods for many months is that they have lost weight. Amenorrhea often occurs when the level of body fat in a girl goes below about 12 to 15 percent. Girls who are athletes -- particularly runners, gymnasts, and dancers -- are more prone to this as they intensify their training. It's also a common consequence in girls who have eating disorders.

83 days without periods is a matter of concern, it may indicate premature failure of ovaries. Stress to contributes towards period changes. I suggest you visit a doctor for proper evaluation of your case. Good luck
