Quick Summary — Pregnancy Week 21 (2nd Trimester) At 21 weeks pregnant, your baby is approximately the size of a carrot (26.7 cm, 360 g) with 133 days remaining until your estimated due date.

🧒 Baby Development

The baby's movements are becoming more coordinated. Eyebrows and eyelids are fully formed. The baby is beginning to absorb small amounts of sugar from swallowed amniotic fluid.

🤰 What Mom Is Feeling

You may feel distinct kicks, rolls, and hiccups! Braxton Hicks contractions (practice contractions) may start — they're irregular and painless. Varicose veins may appear.

💡 Tips for This Week

Count kicks — aim for 10 movements within 2 hours of your most active period. This becomes more important as pregnancy progresses.
