Baby development at week 14
Baby can make tiny expression-like movements. The thyroid is active, and lanugo (fine hair) may begin. Growth becomes easier to measure on ultrasound.
Average size estimates for week 14 are about 8.7 cm and 43 g — roughly lemon. Your ultrasound report and clinician’s dating override any website average.
What you might feel

You are in the second trimester. Two pregnancies at the same week can feel completely different — treat these notes as orientation, not a checklist you must match.
What to track this week
