First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will look at 90 women who choose the etonogestrel implant (Implanon-NXT) for birth control after giving birth. Half will get the implant within 72 hours of delivery, and the other half will get it 4-6 weeks later. Researchers will track side effects, bleeding patterns, satisfaction, and how many women continue using the implant over a year.
