"i began orth tri-cyclen at 18.  the first two or three months i was extremely emotional and would spontaneously sob for no reason on the saturdays prior to getting my period.  after a few months, i adjusted and had a good experience with this pill.  my periods were generally 5-6 days long.  i&#039;ve since began alesse/aviane for insurance reasons. i&#039;ve experienced some hair thinning, which may or may not be caused by the pill.  my periods are light and last 3-4 days.  but i am considering switching back to ortho to see if this helps with my hair."
