"i&#039;ve been on yaz for about 2 years now.  it was my first birth control. about 9 months in i did have some spotting for about 3 months but it was also during a stressful time of my life.  other than that i haven&#039;t had any bad experiences.  because of a thyroid condition i have my period wasn&#039;t regular.  now since taking yaz i have my period down to the hour it starts.  curious to see what is so new about beyaz other than the folic acid."
