"my mirena was inserted in june of 2006. 6 weeks after the birth of my first child. my 5 years with mirena has almost expired.  i am very pleased with the performance of this device. when my mirena was inserted i experienced approximately 5 months of spotting. i have not had a period in over 4 years. since my last period i have experienced light spotting, most common after intercourse. i must say i have no complaints.
