I had mirena removed 2 years ago,
I also had heart palpitations,I am on meds for it and Im having surgery to have it fixed soon,all because of Mirena.
I have SVTs and PVCs,not very nice.
Also had my thyroids removed a few years ago I blame mirena for thet too.
I hate what mirena has done to me.
I started a helpsite all the w's at mirena-side-effects.com
you can read my whole story there.
Hope you get over it quicker than I did.
