160 days late...help...

LilBoweep

My period is usually very irregular but in this past couple months, I had not had my period in 160 days. This could be because I am ‘malnourished’ but I eat about 1 1/2 meals a day with snacks because that’s what I’m used to eat. I am not underweight or over weight, I’m 16, and 96 pounds, being 4/11 feet.

Any body know what’s going on with my body?
