Brief Summary
This is a study for clients presenting for emergency contraception (EC). EC is used to prevent pregnancy after unprotected intercourse. Clients presenting for EC may be offered either the copper or hormonal IUD or oral EC. Current guidelines allow for same-day implant initiation at the time of an EC encounter, as long as oral LNG EC is co-administered. This study will look at pregnancy rates and clients willingness to receive same-day implant + oral EC and same-day IUDs.
