birth control
"I'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's supposed to shorten periods,  but it actually made mine longer! And it'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't work for."
