Baby development at week 9
Muscles and nerves begin practicing tiny movements. Eyes are formed but fused shut. Essential organs exist in early versions and keep refining.
Average size estimates for week 9 are about 2.3 cm and 2 g — roughly grape. Your ultrasound report and clinician’s dating override any website average.
What you might feel
A metal taste, excess saliva, or breast changes can continue. Energy may still be low.
You are in the first 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
- Symptoms, mood, sleep, and energy in your daily log
- Water intake toward a simple daily goal
- Appointment dates and questions for your care provider
