Hi!
If you were my patient, I would advise you that it is common for women to have very little or no period when they have had a Mirena in place for awhile.
If your pregnancy test is negative, you don't have an ectopic pregnancy--an ectopic pregnancy will cause the test to be positive too.
No cause for alarm, unless the pain becomes worse.
Good luck!

I had the merena for over five years. It slows your period down, and then stops it. I only had one friend that was in that small percentage that kept her periods but they were light, good luck
