Participant milestones
| Measure |
Immediate Nexplanon Insertion
An etonogestrel rod will be placed within 15 minutes following the abortion procedure.
Immediate Nexplanon Insertion: Patient will have a Nexplanon inserted within 15 minutes of her abortion
|
Post-op Nexplanon Insertion
Participants in the "delayed" placement group will be asked to return to Magee-Womens Hospital for a post-abortion visit 2-4 weeks following the procedure. Participants in the delayed group will be offered a method of contraception to use in the interim between their procedure and their insertion appointment. At this time an etonogestrel rod will be placed in her arm using standard procedure.
Post-op Nexplanon Insertion: Place Nexplanon at post operative visit rather than at surgery

Outcome measures
| Measure |
Immediate Nexplanon Insertion
n=73 Participants
An etonogestrel rod will be placed within 15 minutes following the abortion procedure.
Immediate Nexplanon Insertion: Patient will have a Nexplanon inserted within 15 minutes of her abortion
|
Post-op Nexplanon Insertion
n=75 Participants
Participants in the "delayed" placement group will be asked to return to Magee-Womens Hospital for a post-abortion visit 2-4 weeks following the procedure. Participants in the delayed group will be offered a method of contraception to use in the interim between their procedure and their insertion appointment. At this time an etonogestrel rod will be placed in her arm using standard procedure.
Post-op Nexplanon Insertion: Place Nexplanon at post operative visit rather than at surgery
