Development

What is developing around week 37

During weeks 37–38, the fetus continues preparing for birth and may settle into a head-down position. Position and readiness are individual and should be discussed with your clinician.

Your body

Changes you may notice

Third-trimester changes can include shortness of breath, heartburn, swelling, sleep difficulty, urinary frequency, breast changes, and contractions. Your clinician can help distinguish expected discomforts from symptoms that need evaluation.

Symptoms vary widely. Absence, presence, or intensity of a symptom cannot confirm that a pregnancy is progressing normally.
