Periods coming and going on Mirena?

[threekids]

I have looked through the archives, but didn't find an answer to my specific question.  I've had mirena for about 2 years, and after initially spotting for a while, was period free.

About four months ago, AF returned, and has been visiting somewhat regularly.

Based on the past few months, I would've expected to see AF a week to ten days ago, but nothing is doing.

I'm not ready to POAS, but wanted to know if my experience was in the realm of *normal*.

TIA.

When I was on the Mirena, my periods were really irregular. They were super light and often would be up to a month "late". It's highly unlikely you're pregnant with a Mirena, so I told myself to stop worrying about it and stop wasting tests.

Mine were very light and averaged about 4 a year. I took many a test just to reassure but usually not until it was a few weeks late.
