I have had my Mirena in for about a month now give or take a day or two. And I hate it! The day I had it put in my doctor said I could use a tampon. Worst pain ever and that includes child birth. Since then I have been to the ER over a pain by my left and right hip bones. They brushed it off. It continued, they finally looked into it with an ultrasound and it turns out I have a cyst on my left ovary. I knew that could happen. But the headaches are unreal and the pain in my hip area is so bad that my doctor actually prescribed me 800mg ibuprofen. I want it taken out but knowing that I am so young and that I specifically went to this doctor because he offered it I am afraid they will try to get me to keep it in. Someone please help!
