"For starters,  I have absolutely NO PAIN TOLERANCE so this experience did make me cry.  But even my own period cramps make me cry.  
The whole procedure was reasonable, it was processed as like getting a check up, they open you up, give a numbing shot, then they open up your cervix opening which automatically makes you have a cramp.  Depending on your cervix size,  you may have one mild cramp or several as they stretch the opening. My cervix was measured and scoped with a camera for depth of where the Kyleena should be placed properly.  Then comes the fun part. You'll have a multitude of various cramp intensity of various pressures as the IUD is placed. Everyone has different experiences. The pain subsides fast and I felt nothing all night."
