"I&#039;ve had my Mirena in for 4 years. The reason I got it in is because I had bad endometriosis pain and symptoms. Since then the 1st couple of months I had a lot of bleeding and cramps but then my  body adjusted to it all and life has been great! I&#039;m able to function properly again and have never felt this good. I don&#039;t get any period bleeding either. Just some light spotting now and then. I love it. Since I&#039;m not ready to have kids yet, I will probably get another one put in soon."
