Same experience for me as Stephie2. On my second Mirena. No bleeding or periods except occasional rare spotting. Which is great because any bleeding is also agonizing for me. I have adenomyosis and endometriosis. The endometriosis has come back several times regardless of the iud and continues oral birth control, but overall it's helped in terms of the bleeding. Worth it for me!

I’m on my second mirena and I do find it helps. Mainly because it stops me from bleeding which is agonising! It didn’t stop the return of my endo though but did help with my periods.

I had the Mirena inserted just over a year ago. The pain didn't go away - it got worse. I found help elsewhere and the endometriosis had grown back aggressively. It takes about 2 to 3 years for the hormone to penetrate through to the tissue, with the use of the Mirena. It's a flawed concept that IUDs help with endometriosis.
