Pregnancy should always be ruled out with a urine pregnancy test prior to contraceptive implant placement. Optimal timing of insertion of the implant to minimize chance of pregnancy is as follows: [16]

  • If no previous method of contraception is being used, insert between days 1 and 5 of menstrual cycle

  • If using oral combined hormonal pills, insert during the hormone-free week

  • If using a progestin-only pills, insert at any time

  • If using injectable contraception (Depo Provera), insert when next injection is due

  • If inserting after a first- or second-trimester abortion, including septic abortion, insert within 5 days

  • If inserting after use of a contraceptive implant, remove old implant and immediately insert new implant during the same procedure [17]

  • If inserting after use of the transdermal patch or vaginal ring, insert on same day as those methods are removed

  • If inserting after childbirth in a breastfeeding mother, insertion at any time is acceptable, either within 24-48 hours of delivery or at the 6-week postpartum visit; studies have not found differences in milk production or content, continuation of breastfeeding, or infant growth based on these different time windows of insertion [14, 15]

  • If the implant is not inserted as directed, the patient should use a barrier method for 7 days
