very bad experience with Mirena that after having it for 1 year (inserted at age of 43, taken out at 44) it looks like caused me an early menopause at age of 45. not one medic looking at the causes of my nausea, pains has thought that mirena might be the cause. Only after having it removed all these symptoms have calmed down but otherwise always punctual periods (before the insertion of Mirena) have not returned ....would not recommended it anyone!! also the Gynea told me that has some other cases with problematic Mirena...
