At what gestational age should follow-up occur to see if placenta previa has resolved?

The correct choice for the gestational age to follow up on whether placenta previa has resolved is 32 weeks. At this point in the pregnancy, the growth of the uterus and ongoing changes may provide a clearer picture of the placental position. Many cases of placenta previa may resolve as the pregnancy progresses, especially as the uterus expands and the placenta may migrate away from the cervical os.

Follow-ups earlier than 32 weeks may not provide useful information about the placental location due to the dynamic nature of changes occurring in the uterus during this stage of pregnancy. By 32 weeks, healthcare providers can assess if further monitoring or interventions are necessary, ensuring both the safety of the mother and the fetus as they approach delivery. This timing allows for appropriate management decisions based on the placental position observed through ultrasound evaluations.
