I have been on Yasmin for two months now. I got the month-long spotting and irritability in the first month. My female coworkers would make a joke out of it and say that I was "yazing-out" when I got moody. In the second month, I noticed my hair is thinning. Dramatically. I thought maybe it could be from stress at work. But, now after reading this site I see others have experienced hair loss too. I thought estrogen was supposed to work against hair loss? Ugh....
