Have had a high hormone implant for the past three years, and prior to that I had a coil. I have decided that I want to go on to some form of pill, as I am really fed up of having bits of metal in my body, and the high hormone implant has made me way too hormonal for my liking (but I have been too squeamish to have it removed, but the three years are up and it's got to come out).
Are they effective/even possible?
