Yes i wanted to know why my period only last one and a half?

Cycle changes: may be due to hormonal variations, stress, tension, anxiety, or illness/nutrition. Simply keep a menstrual diary and of course protect yourself.

Short period: The main reason for light periods is a change in hormone levels. Causes for what seems to be a light period can include: implantation bleeding in early pregnancy, thyroid problems, eating disorders, excessive exercise, initial periods for a girl, use of an intrauterine device, oral contraceptives & perimenopause.
