How is your baby developing at 9 weeks?
Elbows and knees flex; tiny movements exist but you will not feel them. External genitalia are not reliably distinguishable yet. Ears sit low and will migrate. Average length is around 2.2–2.5 cm; weight is only a couple of grams.
What changes in your body at 9 weeks?
A visible vein map on the chest, nasal stuffiness, or mild headaches can appear. Lightheadedness when you stand quickly is common if you are not eating or drinking enough.
Tips for this week
Rise slowly, and add a snack if you feel shaky. Discuss headache remedies — some common painkillers are not first-line in pregnancy. If headaches are sudden, severe, or come with visual changes, seek care the same day.
