These are my exact symptoms. I noticed a couple days ago that I should have my period by now but I do not have it. I know it's normal for Mirena to stop your period (half the reason I got it) but I still noticed PMS symptoms like getting overly emotional at silly commercials. I didn't know if you sill get PMS when you don't get your period while on mirena so I did a simple google search and this was the top hit. After reading your post I was shocked because I have been shaky, cold, anxious, and not feeling too well. I did not attribute any of these symptoms to my mirena. I honestly thought it was due to other things but after hearing you all say you have all of these exact symptoms around the time you should get your period I think there is no coincidence.
