How long do I have to use contraception after menopause?

Am I completely finished the menopause and do I need to use contraception and for how long?
until you have experienced a full year without any bleeding or spotting — no matter how remote the chances of pregnancy at this stage. The difficulty with contraception is that hormone-based options can lead to intermittent bleeding, which means that you are unable to reliably detect when you are no longer fertile.
