I had my first Mirena inserted in Feb. 2008 and just went in today and got another for 5 years. When i first got it is 2008 I spotted on and off for about 6 months or so but after that no more periods not even spotting! Some cramping here and there was about all I dealt with and a few Ibuprofen or Tylenol fixed that. I highly recommend the Mirena to anyone who has had at least one kid and doesnt want anymore for a while or in my case who doesnt want more kids and doesnt want a period

having it removed after 3 months is kind of crazy in my opinion -- give it at least 6. I've had mine for almost 5 years and I'll get another. I did have spotting on and off for awhile.
