Your Pregnancy Week 14

Your Baby

Your baby's body systems are starting to work on their own. The digestive system practices moving food along the intestines and through the renal system and he can create and eliminate urine. He also continues to practice breathing the amniotic fluid in and out of his lungs. Your baby has tiny, soft nails on his fingers and toes, is growing hair and may even suck his thumb. Your baby is approximately 10-11.5 cm (3 1/2 -4 inches) and weighs approximately 1.5 ounces.

Also, your baby's blood is beginning to form in the bone marrow and blood vessels are beginning to connect various parts of the fetus to another. The joints and muscles allow your baby full body movement so your baby is able to move around. The baby's neck is getting longer and his chin is no longer resting on his chest. The eyes and ears continue to move into place. The hands are becoming functional and reflex movements often occur. Nourishment now comes from the placenta. Remember, some of what you eat and drink is getting through to your baby. The doctor can tell if your baby is a boy or a girl using special tests.

Amniotic fluid is an amazing substance. It completely regenerates itself every three hours. We do know that it is partially composed of urine from the baby, but where amniotic fluid in general is made we are not sure. Modern medicine still has some surprises left.

Your Body

Welcome to your second trimester! Levels of hormones are becoming steady and the mood swings of the first trimester will slow. However, because of the lower hormone levels - and the fact that your baby may be pressing against your bowel - you may begin to experience constipation as your intestinal muscles are working more slowly. A good way to combat this is to increase the fiber in your diet. If after a while you see no relief, or you find this bothersome or troubling, mention it to your doctor at your next appointment. Other changes may include the appearance of a dark line down the middle of your abdomen. This is normal and is called the linea negra. Also, the areola (the dark part of your nipple area) may have gotten darker and larger. This is also normal as your body readies itself for breastfeeding. Your uterus is approximately the size of a grapefruit.
