Abstract Objective:

To explore women's experiences with postpartum intrauterine device (PPIUD) insertion and the decision-making process in the postpartum period.

Methods:

A qualitative design was employed with face-to-face interviews using a semi-structured script of open questions. The sample was intentionally selected using the concept of theoretical information saturation.

Results:

Interviews were conducted (1) in the immediate postpartum period, and (2) in the postpartum appointment. 25 women (N = 25) over 18 years old who had a birth followed by PPIUD insertion were interviewed between October 2021 and June 2022.

Three categories were constructed:

(1) Choice process, (2) Relationship with the health team at the time of birth and the postpartum period, and (3) To know or not to know about contraception, that is the question.

Conclusion:

Professionals' communication management, popular knowledge, advantages of the PPIUD and the moment PPIUD is offered play a fundamental role in the construction of knowledge about the IUD. Choice process did not end in the insertion.
