"i was put on this pill because my obgyn believes i may be prone to polycystic ovaries and had very long, heavy periods. i had taken other birth controls in the past (yasmin and nuvaring - about 10 years ago). in my first month i&#039;ve experienced migraine-like headaches and almost daily nausea, which subsided during my hormone-free week. i take the period at night, but if i have to stay up for a significant amount of time after i take the pill, i have to deal with terrible headaches. my period was still long (about a week) but was much lighter than before. i&#039;ve read that the side effects may subside after a few months, so i&#039;ve chosen to stick with it for now. gave it a 6 because other pills could have the same efficacy without the side effects"
