Abstract

Case reports of pregnancies with inadvertent etonogestrel contraceptive implant exposure in the first-trimester have not demonstrated teratogenic risks or adverse pregnancy outcomes. We report the clinical observations of a 15-year-old nulligravida who continued her etonogestrel contraceptive implant throughout pregnancy and delivery, without any adverse maternal or neonatal outcomes. The patient then continued her contraceptive implant as a reliable postpartum contraceptive method. Although her favorable outcomes are consistent with available pharmacologic literature, more data is needed regarding maintenance of a contraceptive implant during a desired pregnancy.
