By now you are starting to feel a bit ungainly as your centre of gravity shifts and your stomach continues to grow larger. Try to stand up straight and practice good posture at all times. Your ribs may begin to feel sore as the baby pushes up against them, and those constant trips to the loo return as baby presses on your already-cramped bladder. Your naval will disappear, and you may have a dark line, called the linea nigra, running down your abdomen. You may have difficulty sleeping, both because of your size and because of the activity of your baby. Rest as much as you can! You may begin antenatal classes, and now is a good time to shop for baby.
Your baby is about 16 inches long and weighs around 3.5 pounds. His face is now smooth, and he will be laying on fat stores over the next weeks in preparation for life outside the womb. Most babies will have turned head down by this time in preparation for birth. If your baby were to be born now, he would have an 80 per cent chance of survival.
