birth control
"I'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'm asking if I'm taking this pill everyday at the same time and period is coming. Some headaches with it. So 'Im not happy at all. Thinking to change for another pill. Maybe the body got tired of  taking the same one."
