Your baby's crown to rump measurement is about 0.56 to 0.8 inches (14 to 20mm).
Your baby's face has a recognizable shape with eyelids and the tip of a nose with formed nostrils, though his head is still very large compared to the rest of his body.
All major organs are now formed and in place, though they still need to mature.
A tongue has already formed. The ears are forming both internally and externally.
The arms and legs extend forward and shoulders, elbows, hips and knees are detectable. Knees and elbows have begun to form on the limbs. Tiny fingers and toes are starting to appear at the tips of your baby's developing limbs and the arms may be slightly flexed at the elbows and wrists. All major organs are in place.
Your baby is moving around a lot, moving his legs and flexing his spine, but you are unable to feel it at this point.
Your baby's genitals have begun development, though they are still difficult to identify.
Your baby measures about 0.9 to 1.2 inches (2.2 to 3cm) from crown to rump.
Your baby's arms and legs are longer and her hands are flexed at the wrist. The head is growing more erect and the neck is more developed. On an ultrasound, you may see your baby moving, though you still can not feel this.
The organs are forming. Ears are developed and the eyelids have begun to cover up your baby's eyes. Hands and feet appear as well as small buds which will become fingers and toes. The paddles of your baby's hands have clearly defined finger ridges now, with the tissue between them (which previously made them look webbed) dying off to leave separate fingers.
Your baby's back has started to straighten slightly and the tail is now shrinking. The head still seems large and is curved forwards on her chest. Your baby is starting to look like a tiny person!
