About this trial
This study aims to evaluate long-term outcomes when the etonogestrel contraceptive implant is inserted at an alternative site located over the scapular. The study will evaluate the pharmacokinetics (i.e., drug levels) and side effect profiles of participants who have an etonogestrel contraceptive implant inserted at this alternative scapular site over the course of at least two years.
