Your BabyThis is another busy week for your baby. Your baby now has a head and trunk. A groove (known as the laryngotracheal groove) forms and will become the larynx or voice box while the beginnings of the mouth and digestive system are evident as well. The inner ear and blood circulation are also apparent and your baby is beginning to develop facial features as indentations form that will become the eyes, ears and mouth. Your baby's brain is developing and activity can actually be monitored on an electroencephalogram (EEG). Also developing are the limb buds that will develop into the arms and legs. Your baby's heartbeat is visible on ultrasound as the heart is bulging from the body. The length of your baby is about 4 - 6 mm or 0.15 - 0.24 inches.
Your BodySorry to tell you this, but as your rise, you may see your nausea, vomiting and headaches get worse this week. While it is called morning sickness, you may experience it at night or even in the middle of the day. There will be many changes in your body, but this week the changes are most apparent in your breasts. These breast changes may include increased breast tenderness, a tingling sensation, a darkening of the areola (the dark nipple part of your breast) and they may feel heavier then normal. The levels of pregnancy hormone are enough that urine tests that measure hCG will show a positive result at this point. You're sure to be able to confirm what your body is telling you.
