abnormal uterine bleeding
"I'm 16 years old with no kids. The insert of the Mirena was very painful, and I mean so painful that I teared up and felt very dizzy after. I have used birth control pills in the past for heavy bleeding and cramping but I got break through bleeding. The first day of getting it inserted was probably the worst day, now I'm just spotting! But I do recommend this device to other teens/women who have heavy periods!"
