At about 26.7 cm from head to heel, your baby is close in length to an Anemone (~25–30 cm): a bright bloom held on one graceful stem.

Anemone (~25–30 cm) — this week’s plate, drawn at your baby’s scale.
How big is the baby at 21 weeks?
About 27.4 cm (10.8 in), measured head to heel — the size of a anemone.1
Fine, downy lanugo is developing, along with hair and eyebrows. Your baby can also hear noises and voices beyond the womb now.
21 weeks pregnant is how many months?
Week 21 falls in the fifth month of pregnancy. Weeks and months don’t divide evenly, and your antenatal care counts in weeks — so Zohra keeps weeks, and prints the month for the relatives who ask.
That puts you in the second trimester (weeks 14–27).
What might you be noticing?
Sleep shifting. tiredness and broken sleep can still be part of this week.
Digestion taking its time. heartburn, bloating, or constipation may be showing up.
Body adapting. backache, leg cramps, and feeling warmer are listed among common symptoms.
