"i&#039;ve been taking it for 4 months now. after 4 months i can say that my body has adjusted pretty well to these meds. the first 3 months i suffered with very tender breasts, headaches, breakthrough bleeding, bloating, and nausea, but month 4 has been a breeze. i&#039;m 28, had never had a menstrual cycle, extra hair growth, abnormal hormone/thyroid levels. this has worked wonders for me. just give your body 3 - 4 months to adjust to it! my cycles are regular and last 5 - 6 days now."
