I started my periods at the age of 13 (I'm 17 now) & up until 6 months ago my periods were regular (every 28 days) & they always lasted for 4/5 days. Suddenly, I've started having really irregular periods. They happen every 14-20 days and last 7-10 days a time. I've also experienced gradual weight loss. I'm not sexually active. Should I be worried?

Yea u shld b worried 14 days r too much and must consult a gynecologist and u must strt doing yoga exercises
