this thing sounded like the healthier alternative to the shot. i researched the heck out of it and decided it was for me. my "favorite" bit of information was what i learned minutes AFTER my mirena was inserted...the part where i have to go hunting for the wires everytime i have a period!!! if youre like me that was once every other week for the first 5 months. I have had serious thoughts about removing this ridiculous thing myself! You know, while im in there looking for those wires to make sure theyre still there!!
