Oh My - My back and leg has been hurting so bad lately. I've had the Mirena for aprrox. 2 years. It was time for me to replace my copper IUD but what I didn't know is that my doctor replaced it with the Mirena without my consent until the procedures was over. I recently had a pap and my gyn couldn't find the string. I hope that it isn't lost in my body. I can't help but think the worst. I've decided to just get the thing removed and have my tubes tied. I like the fact that I don't have menstrual cycles but the pain in my back and legs are too much for me lately.
