I had the Mirena inserted on Sept 29 and today is Oct 6. The reason for having it was that my cramps were SO bad during my periods and the GYN could find nothing wrong with my insides after an exploratory laporascopy. Now I sit here looking through all this information because I'm cramping up so badly. I'm glad I found this site and will continue to check it. I think I'll give the Mirena a little more time but I can only imagine how I feel when I get my period for real. The cramps I had before put me on the ground. My GYN said to come in tomorrow to have an ultrasound and check to see if it's in the right place. Hmmm
