A friend of mine got one and she had to have her legs in stirrups. They were electric ones and something happened and her legs were moved the wrong way and she's had problems ever since with her hips (this happened a few years ago). If you get it then watch for this and if anything feels uncomfortable let them know straight away.

If you have a health care card it should cost $5. I looked into it but decided to get an implanon instead which lasts 3 years instead of 5 and on healthcare card only cost $5 as well. My GP put it in but not all GPs are qualified to do it.
