"i&#039;ve been taking it for 3 years, i rarely miss days and i take all pills (some people don&#039;t take the brown pills). i haven&#039;t had my period since 6 months after taking the pill. it&#039;s amazing. my first month i had extremely bad migraines but not any more. i love that they are chewable so i take it in the morning after brushing my teeth."
