Planning checklist & guidance

  • Confirm pediatrician selection and hospital preregistration paperwork.
  • Review kick counting or movement monitoring instructions from your team.
  • Discuss Tdap timing, Group B strep testing, and signs of labor.
  • Pack hospital bags by 36–37 weeks if possible; keep car seat installed per instructions.
  • Know after-hours triage numbers and when to go straight to L&D.

How to use this page with your pregnancy timeline

When you travel across time zones, your “weeks pregnant today” number does not change because the airplane crossed midnight—but fatigue, swelling, and access to care can. Keep a printed summary with EDD and gestational age.

Mental health is prenatal health. If sleep loss, panic attacks, or low mood persist, ask for referral options the same way you would for physical pain. Crisis lines exist if you need immediate support.
