If you have had unprotected sex or believe your contraception has failed, don't panic, you can get help but you must act quickly.
Emergency contraception is available in different forms - Emergency Hormonal Contraception (EHC) and an IUD (Coil).
There are two types of EHC, one which can be taken up to 72 hours, (3 days), after sex, and one which may be effective for up to 120 hours, (5 days). However, the sooner you take them the more likely they are to work.
An IUD can be inserted up to 5 days after unprotected sex, and can remain in place if you want to use it as a long term method of contraception.
