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
- The top of the uterus (fundus) is now roughly at the level of the belly button
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.
When to get help now
Contact your maternity unit now, even at night, if your baby is moving less than usual or the pattern has changed, you have any vaginal bleeding, fluid leaks from your vagina, you have regular or painful contractions before 37 weeks, or you have a severe headache, vision changes, pain just below the ribs or sudden swelling of the face, hands or feet. Do not wait until the next day.
