Hey hun.. I had mine out a few weeks ago.
I had it in for a year.. and it was pretty bad: constant bleeding for months, headaches, crippling cramps (something I never got) and no sex drive.
It was also making me constipated to the point I was back and forward to the docs every other week. So I decided to get it out.
Speaking from expierence.. you get a local, which numbs where the implant is. They then make a small cut and take it out. You can 'feel' what they are doing however it is totally pain free aside from the prick from the local jab.
Hopefully this helps x
