Mirena iud -1 year no period?

Cyndi

I got the Mirena iud places a year ago.

I noticed my last 2 periods my blood was getting lighter in color and flow.

This month, I haven’t bled.

I’m concerned about me being pregnant. Or if this is the normal time for my periods to stop because of the Mirena.

For those of you with Mirena, and if your periods have stopped, what was it like when it was slowing down/ during you “flow” days
