Your baby is about the size of a lipstick tube at this point; weighing in at about 9 grams and measuring around 2 inches long. With a dopler, a handheld sound wave stethoscope, you should be able to hear the baby’s heartbeat at this point. All of the critical development is done at this point, now all that needs to happen is for your baby to grow.
Right now, your baby’s head is about half of it’s length. The forehead bulges and sits very high on the head. On an ultrasound you would be able to see the clear outline of the spine. Spinal nerves are stretching out from the spinal cord.
The reproductive organs develop very rapidly this week. The external genitals are developing into either a penis or a clitoris and labia majora. By the end of the week these external genitals are recognizable and it should be easier to see if parents are having a boy or a girl.
All of the vital organs are functioning by the end of the week. Kidneys are producing urine and the pancreas is producing insulin. At this point, only growing and becoming more efficient is left to do.
