Yes, an Intra-uterine Copper Device (IUD) can be fitted as emergency contraception by a family planning clinic or trained doctor up to five days after unprotected sex. However, 72 hours or more must have passed since the unprotected sex for this to be an alternative option. It must also be worn until your next period. It is 99% effective and can remain in place in place as a form of contraception for 5-10 years. It may be more suitable to you if you have taken certain prescribed medicines within the last four weeks. However, its one big disadvantage is that it can cause some women to have heavier and longer periods.
