What to Expect

  • Body changes

    Backaches, swelling, Braxton Hicks contractions

  • Fetal development

    Baby gains weight, lungs mature, prepares for birth

  • Common Concern: Baby’s Movement

    Your baby should move regularly in the third trimester. If you notice fewer kicks or a change from what feels normal, call your doctor right away. Some parents use tools or apps to help track their baby’s movement.

  • Between 36–37 weeks: Expect a Group B Strep test.

  • Install an infant car seat before your hospital stay. You need one to leave the hospital!

  • Plan where you'll recover after you give birth at least 30 days before your due date.

  • Discuss your birth plan and pain management options with your doctor.

  • If you pass your due date, talk about induction.

  • Pack a hospital bag with essentials for you and your baby.
