I had no pain getting mine removed- they use a local again, same as putting it in. It did bruise though.

I had weird cycles for about 3 months. About a month after it came out I had a few days of dark brown heavy spotting but no real period. Then I think I had spotting of red blood a couple of times but it wasn't until about 3 months after it came out that I had a proper period and then they were regular.
