I got an IUD placed about five months ago, two months after giving birth to my daughter. I am breastfeeding her, so I didnt have a period until three to four months after delivering. When I finally got my period, I regreted getting the copper IUD because my period was full of cramps and I soaked through tampons and pads just about an hour at a time, and this would last for about a week....when normally, I would never have cramps at all and my period ended in three days flat.
Today, I started having this really bad cramp in the lower right side of my abdomin. It was hurting so bad that I had trouble breathing...like I was about to cry. It went away afterwards, but after nursing my daughter, it came back.
The reason why I am concerned is because I know that breastfeeding causes uterine contractions, and I haven't been having any pains until now. Could there be something wrong with my IUD? Could it be expelling or lodging into my uterus???

Maybe I'm over reacting, but the pain is so bad that I had to be concerned about it.
