The purpose of this research study is to test the levonorgestrel intrauterine system as a method for emergency contraception. Emergency contraception refers to pregnancy prevention after an act of intercourse.
While the levonorgestrel intrauterine system is approved as a contraceptive method, it is considered investigational as emergency contraception, which means that it has not been approved by the U.S. Food and Drug Administration. This study will compare the device to the most common types of emergency contraception, oral Ulipristal acetate, or oral levonorgestrel. The oral levonorgestrel regimen was approved as a method of emergency contraception by the U.S. Food and Drug Administration in 1998. This method involves taking a 1.5mg pill of levonorgestrel in a single, one time dose. The Ulipristal acetate was approved as a method of emergency contraception by the U.S. Food and Drug Administration in 2010. This method involves taking a 30mg pill of Ulipristal acetate in a single, one time dose.

Experimental: Levonorgestrel Intrauterine System
Participants randomized to the levonorgestrel IUS will undergo placement at the time of randomization. They will follow-up with a self-administered urine pregnancy test 5-6 weeks following.
Device: levonorgestrel IUS
Levonorgestrel IUS, 52mg placed intrauterine
Active Comparator: Ulipristal acetate
Women in this arm will receive the oral Ulipristal acetate (Ella) regimen, which is currently the most effective method of oral emergency contraception.
Drug: Ulipristal acetate
30 mg tablet
Other Name: Ella
- Pregnancy [ Time Frame: 6 weeks ]The primary outcome of this study is unintended pregnancy following emergency contraception
- LARC use at 6 and 12 months [ Time Frame: 12 months ]Long acting reversible contraception (LARC) use at 6 months following method allocation will be evaluated.
- Continuation and satisfaction among participants in the LNG-IUS arm [ Time Frame: 12 months ]Continuation and satisfaction among participants in the LNG-IUS arm
