What is an IUD as emergency contraception?
The IUD can be fitted after unprotected sex to prevent pregnancy occurring. It must be fitted within five days of unprotected sex or five days after ovulation. It can be left in as a form of contraception or removed after a normal period. It may stop an egg being fertilised or implanted in the uterus. The IUD is not suitable for all women. A doctor will discuss whether this method is suitable for you. The IUD is 98% – 99% effective. For more information, download a copy of the Marie Stopes International Contraception Fact Sheet .
