Welcome to HCM,
You haven't mentioned the color of bleeding.
During menstrual period the color of bleeding is bright red and it contains many clots in it.
The amount of blood lost during a period ranges between 20-80 ml.
If amount of blood lost during period is less than 20 ml, it can be taken as light period.
At your age the cause can be like stress
, excessive exercise, eating disorder
imbalance, use of contraceptive
pills, PCOS, autoimmune disorder etc.
To establish diagnosis, thorough examination and some investigations are required.
Thus, you should consult a Gynecologist in person for examination.
