The baby’s bones are becoming more rigid. Its hands are fully operational, complete with tiny fingernails and fingerprints. Your baby is using these hands to discover different body parts – but just sensing, the eyes remains closed. The lungs will begin to produce a substance that lines the air sacs – it allows them to inflate easily and keeps them from collapsing and sticking together when deflating. Now the eyes are fully developed with eyelashes to protect them after birth. But the eyelids are still closed.
Welcome to the third trimester, your uterus is the size of a soccer ball and the top of it is about halfway between your bellybutton and your breastbone (the bone where your ribs come together). This is also the week when many pregnant women experience the return of fatigue, dizziness and an urge to go to the bathroom. At night, you may wake up with a tightening sensation in your calf - aaaaaa cramp! It could be one of the nastier ways of getting woken up. Massage carefully to release the cramp.
