Development

What is developing around week 34

Around the 32-week source checkpoint, bones are formed but remain soft, practice breathing movements occur, and the body stores minerals while weight gain accelerates.

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.
