I have struggled with irregular periods from the day I got my first at age 13 until I was finally prescribed Emoquette at age 23. Since taking Emoquette, my period is always on time(the week in the pills that you should recieve your period). I have also noticed a difference in the severity of my periods, they are lighter and less painful. Just wanted to put this out there because I see a lot of bad reviews of this drug, but for me it is a life-saver! Thanks!
