Brown = old blood.: 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.

Old blood: mixed with normal vaginal and cervical mucous. I suggest keeping a menstrual diary and certainly use birth control unless planning a pregnancy.
