Well just like many of you I am glad that I am not going crazy. I had the Mirena inserted in April and have had sever bloating continous brown "periods" to small for a tampon and extremely sore breast. When I went to my GYN and discussed bc I had said that I had heard about the Mirena and asked her what she thought. She gave me the I think it would be the best form for you.She said the first few months would be irregular periods but then they would either be very light or none at all. Well they have been light but they go on for 2 weeks. I am also experiencing fatigue and dizziness and mood swings. If I didn't know any better I would think I was pregnant. I am unable to focus well on things. Feeling absent minded klike I was during my pregnancies. I have gained some weight and I and constantly bloated. My doctor told me that I would experience some acne which fortunately has been minimal but that there were very little side effects!! Bull!! I think I am going to scheduled my removal ASAP
