hello.. wow.. this site is unreal i mean i never found this UNTILL after starting yaz.. iv been on it for only like 7 days and from the 4th day iv started having terrible "head squeezing" "migraine" & attacks.. feel "nausiated" and "irratable".. i went on this at the advise of my obgyn after delivery of my baby..my major purpose was to get rid of the excess "hair growth" etc "due" to "PCOS".. ill be visiting my doc today to see was else she can advise instead of yasmin.. its funny how they prove to be synthetic ingredients and with least or no side effects.. what a load of bull****!
