By the time you're 7 weeks pregnant, your baby's:
- Elbows and toes can be seen
- Digestive tract and lungs are developing
- Hands and feet are developing but look like paddles
- Brain cells are rapidly being produced
Your baby’s face is also starting to develop. The outline of nostrils, eyes, ears, and a mouth becomes clearer.
Your baby has doubled in size since last week and is now about the size of a blueberry (around a half-inch long).
The umbilical cord that links you to your baby throughout pregnancy fully forms during this week. The umbilical cord:
- Supplies oxygen and nutrients to your baby
- Removes your baby’s waste matter
