Looking ahead
You're entering the home stretch—most pregnancies conclude within the next 2-3 weeks. At week 37, your baby is considered full-term, meaning their lungs and organs are ready for life outside the womb. Pay attention to any signs of labor and stay in close contact with your healthcare provider.
