Mirena and fist

I just had my Mirena put in yesterday1-17-08. It was very painful, the doctor had to dilate me 4 times, because she said I am small. Then she had trouble putting it in because of my retroverted uterus. about 30 minutes after I left I had cramps and my entire left leg hurt bad. My toes tingled, and my whole leg was in pain all night, today it has been off and on. Also I have noticed being short of breath. I am already regretting this decision. I have had no energy which is odd for me. I can feel the Mirena in there, I am worried that it will hurt me because I am smaller than average (4'11" and 104 lbs.) my husband and I have a 14 year old son and don't want anymore kids, but condoms are driving us crazy and it scares me because I am 35 and do NOT want to have a baby at my age. So I thought this would be perfect while we decide on something more permanent. I am going to give it one more week and If I don't feel any better it is coming out!!! I am so glad I found this site, because the doc already told me that my leg pain has nothing to do with the iud even though it started right after I got the iud, she told me to go to a chiropractor or my family doc, because she said it had to be something else. I don't believe her.
