birth control
"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've since began Alesse/Aviane for insurance reasons. I'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."
