Which suffix indicates a relationship to just having given birth?

The suffix that indicates a relationship to just having given birth is "postpartum." This term specifically refers to the period following childbirth and is used to describe various aspects related to the mother's recovery and the care of the newborn immediately after delivery.

In contrast, "gravida" refers to a woman who is pregnant, and it does not pertain to the post-birth period. "Gestation" refers to the carrying of an embryo or fetus during pregnancy, focusing on the time prior to birth. "Neonatal" pertains to the period immediately after birth for newborns, generally defined as the first 28 days of life. Thus, while all these terms are related to pregnancy and birth, "postpartum" specifically addresses the time after childbirth, making it the correct answer for this question.
