Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: early insertion
Postpartum women into whom the etonogestrel-releasing contraceptive implant (Implanon®, N.V. Organon, Oss, Netherlands) will be inserted in the first 48 h postpartum. The ENG implant will be inserted subdermally in the non-dominant arm of volunteers upon local anesthesia with 2% lidocaine with vasoconstrictor, according to the manufacturer's instructions.
Drug: early insertion
Postpartum women into whom the etonogestrel-releasing contraceptive implant (Implanon®, N.V. Organon, Oss, Netherlands) will be inserted in the first 48 h postpartum.
Active Comparator: conventional insertion
Postpartum women into whom the etonogestrel-releasing contraceptive implant (Implanon®, N.V. Organon, Oss, Netherlands) will be inserted after 6 week of the delivery. The ENG implant will be inserted subdermally in the non-dominant arm of volunteers upon local anesthesia with 2% lidocaine with vasoconstrictor, according to the manufacturer's instructions.
Drug: conventional insertion
Postpartum women into whom the etonogestrel-releasing contraceptive implant (Implanon®, N.V. Organon, Oss, Netherlands) will be inserted in the first 6 week of delivery.
