Women using an emergency contraceptive method must use back up protection for 1-2 weeks depending on method. The Copper-IUD is the most effective emergency contraceptive method. The investigators wish to explore if women choosing the Cooper IUD have a higher frequency of use of an effective contraceptive method 3 months and 6 months after the use of an emergency contraceptive method than women who choose to use the emergency contraceptive pill EllaOne (ulipristal acetate).
