I had Mirena from may of 07 to sept of 08...and I didnt have one period during the whole time! When I got it removed in sept, I had bleeding from the removal but still no periods! And now it is January and I am 6 weeks pregnant...go figure. But to answer the ? mirena is a strange little thing that works in strange ways. There was a time that I thought I was preggers as well on it but it was just my body reacting...Check to see if your strings are still there, and take a pregnancy test if you are still unsure...and if that doesn't satisfy, call your doc and see what he says!
