This week your baby is about 9 1/2 - 10 1/2 inches in length (crown-to-rump) and weighs almost 1 3/4 pounds. This week your baby's heart should be so strong that it may be possible to hear his or her heart beat by placing an ear on your belly.
The retinas (in your baby's eyes) have developed all the layers they will have at birth and your baby's eyes are blue, no matter what race because the pupils don't acquire their final color until a few months after birth. Besides being wrinkled, your baby's skin is also transparent and very thin, but it's starting to thicken gradually and smooth out.
While premature babies have a long difficult road ahead of them, if your baby was born this week he or she would have a good chance of survival, because of improved medical advancements.
Your uterus is approximately 2 inches above your belly button and you may have gained around 15-22 pounds so far. As you get bigger you may suffer from a number of discomforts, including back pain, because of the strain of your growing belly. Backaches can also be caused by your body preparing itself for labor and delivery by loosening your joints. Make sure you always bend at the knee, not at your waist and walk barefoot as much as possible, avoiding high heeled-shoes. Sleeping with an extra pillow between your legs at night may also help.
