    Pregnancy Week 30

    Real, evidence-based guidance for exactly where you are right now.

    This page provides general, educational information based on published clinical guidelines (ACOG, WHO, RCOG, CDC, and others — see References below). It is not personalized medical advice and does not replace your own doctor's guidance for your specific pregnancy.

    Baby Development

    The brain is developing rapid, distinctive folds and grooves — real, structural growth that continues after birth too.

    Your Body This Week

    The bump is now substantial; sleep may be more difficult as comfortable positions become harder to find.

    Diet

    Continue a varied, nutrient-dense diet.

    Supplements

    Continue your prenatal vitamin.¹

    Tests

    Routine follow-up.

    Vaccinations

    Tdap, if not yet given, remains within window.⁵

    Exercise

    Continue regular, moderate activity as comfort allows.²

    Red Flags — When to Call Your Doctor

    Reduced fetal movement, regular contractions, or fluid leakage warrant urgent medical attention.

    Doctor Visits

    Routine follow-up as scheduled.

    Mental Health

    Sleep difficulty can genuinely worsen mood and fatigue — a pregnancy pillow and side-lying position can help, and it's worth mentioning to your doctor if it's significantly affecting you.

    Frequently Asked Questions

    What's the best sleeping position now?

    Real, current guidance favors side-lying (either side), which supports healthy blood flow to the uterus — a pregnancy pillow between the knees and behind the back can genuinely make this more comfortable.
