"i&#039;ve been taking minastrin for 4 months now, and it has having total opposite effects on me than what my doctor said it would. it&#039;s supposed to shorten periods,  but it actually made mine longer! and it&#039;s supposed to help reduce cramping  but it actually worsened my cramps. i also have more mood swings, and nausea. i guess i just turned out to be that small percent of the statistic that it doesn&#039;t work for."
