I actually just got it a few weeks ago. I have not had any kids/never been pregnant. The day it went in, it was quite uncomfortable. They suggest taking a couple motrin an hour before. By that night, I felt pretty much back to normal. A bit of heat and babying myself, and life was back to normal.
They trim the strings quite short (the nurse practitioner said 2cm). My husband and I have had a test run with it, and he said he couldn't feel it and like your man...he is blessed in that dept, so he would have if the strings were too long.
I haven't gained any weight with it, and in fact, I feel much better about it than I did with the pill.


Seems like the Mirena strand has retracted up somewhere in my cervix.
