    Baby this week

    • Lungs are fully mature and ready to breathe air
    • Settling into head-down position for birth
    • Practicing breathing movements and swallowing
    • Skin is smooth and less wrinkled as fat deposits increase

    You this week

    • Increased Braxton-Hicks contractions, some becoming irregular but intense
    • Pelvic pressure and heaviness as baby drops lower
    • Frequent urination and possible urinary urgency
    • Difficulty sleeping due to discomfort and anticipation
    • Cervical changes that your provider may monitor
    • Possible bloody show or mucus plug loss

    This week's tips

    • Stay alert for signs of labor—regular contractions, rupture of membranes, or vaginal bleeding—but don't panic about every symptom
    • Rest when you can; labor is physically demanding and sleep now will help
    • Keep your hospital bag packed and in an easily accessible location
    • Practice comfort measures you plan to use during labor: breathing techniques, positions, heat/cold therapy
    • Time contractions if they occur, but don't obsess; most aren't true labor yet
    • Eat nutritious meals and stay hydrated to maintain energy reserves
    • Take short walks if comfortable; movement can help with positioning and endurance

    Looking ahead

    You're in the home stretch. Most babies arrive between weeks 38-40, though some take a bit longer. Your provider may discuss what happens if you go past your due date, including monitoring options and induction timelines.
