I have had my IUD for 3 years now, and I feel sooo pregnant! Symptoms include nausea, severe fatigue, cramps, sometimes sharp pains, and flutters every once in a while! Someone please tell me if you went through this and turned out to be pregnant. I also would like to know how long is mirena really good for?

No birth control method is 100% effective. We have a few members on this site that got pregnant while on Mirena.

It's entirely possible to get pregnant any time you have sex, protected or not.

Try a pregnancy test.
