By the end of this week your baby will be almost 2 inches long and the back of the brain is clearly visible through the tissue of the head. The baby's sex will be determined this week with the testes of a boy or the ovaries of a girl being created with the difference in both being visible.
This week the baby's body is also hard at work on the bones and joints and although at present there is only cartilage, in a few weeks real bones will be made and the skeleton will begin to take shape. Although there are at present only tiny phalanges connected by a membrane, it is still possible to count the tiny fingers of your baby. The baby's heart now beats rapidly and his brains begin to function. The baby now has eyes but no irises and his eyelids have not yet formed meaning his eyes are always open but he sees nothing.
Although your baby can move around now you still won't be able to feel it. You may find you gain more weight now, not because of the size of your uterus but because the pregnancy hormone hCG causes your intestines to swell a little.
You will soon be visiting your midwife for the first time. This is usually arranged between the 10th and 12th weeks of pregnancy. It is important that you prepare for this meeting as the midwife will need information regarding your general health and the health of your family including any hereditary diseases. You will also have your weight measured, a small vial of blood will be taken and you will need to bring a sample of your first urine of the day. The monitoring of your weight, your urine and your blood will continue throughout your pregnancy.
It is also important to note that during pregnancy you cannot have any x-rays done and you should also inform your dentist you are pregnant as this affects certain treatments such as anesthesia.
