20 WEEKS PREGNANT
The halfway mark — movements become easier to feel
Baby this week: about 25 cm — measured head to heel, since the fetus is now too curled up to measure crown-to-rump easily · about 300 g
≈ 25 cm — about the size of a banana
Illustration enlarged for clarity — the amber marker shows true relative size
Your baby this week
- Measurements switch from crown-to-rump to head-to-heel, which is why the length jumps this week
- Hair, eyebrows, and eyelashes are visibly growing in
- Swallowing amniotic fluid helps the digestive system practice its function
- Movements are becoming stronger and more regular, often described as kicks or rolls
Your body this week
- This week marks the halfway point of a typical pregnancy
- A detailed mid-pregnancy anatomy scan is often scheduled around this time
This week's tip: Ask your provider about the anatomy scan if it hasn't been scheduled yet — it's a good opportunity to check growth and development.
