Your baby now weighs around 1.5 lbs (700g), and measures about 8.8 inches (22cm) from crown to rump, but this varies from baby to baby.
Your doctor should be able to hear your baby's heartbeat, using a stethoscope or Doppler ultrasound device. If your partner puts his ear right on your belly in the right position, he might even be able to hear it unaided if there is no background noise.
Your baby sleeps and wakes in a more regular pattern now. You may notice that your baby is particularly active when you are resting.
The center of your baby's bones are beginning to harden.
If your baby is a boy, the testes will start to descend into the scrotum now. If your baby is a girl, the vagina will begin to hollow out and mature now.
Your baby can make a fist now and may already have a preference for the right or left hand.
With modern medical technology, your baby would have a chance to survive if it were born now.
