    Baby this week

    • Practicing breathing movements with amniotic fluid

    • Bones are hardening, though skull remains flexible for birth
    • Toenails and fingernails are fully formed

    You this week

    • Increased Braxton Hicks contractions (practice contractions)
    • Lower back pain and pelvic pressure
    • Difficulty sleeping and finding comfortable positions
    • Shortness of breath as baby takes up more space
    • Frequent urination and possible leaking with coughs or sneezes
    • Swelling in feet and ankles
    • Fatigue despite needing rest

    This week's tips

    • Start perineal massage (or ask your partner to help) to potentially reduce tearing during delivery
    • Practice different labor positions: squatting, hands-and-knees, side-lying—find what feels good
    • Invest in a pregnancy pillow to support your body while sleeping; try side-lying on your left side
    • Stay hydrated and eat frequent small meals to manage heartburn and maintain energy
    • Pack your hospital bag now so you're not scrambling if labor starts early
    • Take a childbirth class if you haven't already—knowledge reduces anxiety

    Looking ahead

    In the coming weeks, baby will continue gaining weight (about half a pound per week), and you may experience stronger, more frequent Braxton Hicks. Your healthcare provider will begin checking for baby's position and may discuss your birth plan in detail.
