"i&#039;m taking nora-b for almost 2 years. first year was great 8 months no period and than suddenly the period start to show up every 6 months, than 3 months. so i&#039;m asking if i&#039;m taking this pill everyday at the same time and period is coming. some headaches with it. so &#039;im not happy at all. thinking to change for another pill. maybe the body got tired of  taking the same one."
