Changes occur during 17th week of pregnancy

Baby's Development -

  • At about 13 cm from crown to rump and weighing 4.9 ounces (140 grams), baby is still very tiny.
  • The placenta, which nourishes the fetus with nutrients and oxygen and removes wastes, is growing to accommodate baby. It now contains thousands of blood vessels that bring nutrients and oxygen from woman's body to baby's developing body. 
  • Baby's kidneys have started producing urine, most of which travels through the placenta for mother's body to deal with.


Woman's Body -

Woman may notice that her breasts have changed considerably since her pregnancy began. Hormones are preparing breasts for milk production — more blood is flowing to the breasts, and the glands that produce milk are growing in preparation for breastfeeding. This can increase breast size and cause veins to become visible. Woman may be able to hear her baby's heart beating when examined. The second trimester is usually regarded as the best time in pregnancy for traveling and getting out.
