For the first few days I felt awkward and sick knowing it was there. But it was all in my head and I got over it. However, I had never previously charted and so it was easier for me to "forget" about the IUD than I think it would be for a woman who has a closer relationship with her cervix.
As for getting it out, no big deal at all. My midwife had it in her hand before I realized she had even found the strings. It seriously took like two seconds and I hardly felt anything.
