Baby development at week 11
The skeleton begins ossifying. Hair follicles and nail beds appear. Diaphragm practice and hiccup-like motions can start even if you cannot feel them.
Average size estimates for week 11 are about 4.1 cm and 7 g — roughly fig. Your ultrasound report and clinician’s dating override any website average.
What you might feel
Round ligament twinges or bloating can appear. Clothes may feel different before a clear bump.
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
