Hi everyone, I had Mirena pleased about 2 years ago following my 2nd child. I have been experiencing mood swings, dizziness, nausea, and breast enlargement. I feel as though I am pregnant (which I know is rare). I've been suffering from sharp chest pain at times and sharp abdominal pains. Cardiology testing came back normal. I have no sex drive and feel as though I cant lose the weight gain from pregnancy #2. After pregnancy #1 I was able to lose all the weight in a matter of 10 months without trying. I know that this IUD has more side effects then what the doctors are informing us. It is crucial that any woman that has this IUD report all side effects to their MDs. This way it is documented for future research.
