How long does it take for contraception to start working?

When you start a new hormonal contraceptive, you might not be protected against pregnancy straight away. You might need to use extra protection, like condoms, for a few days before your main contraception starts to work. It depends on when you start it and what kind of contraceptive you’re using.
