5 Weeks

I found a very neat website that summarizes what is happening to our little lovebug each week.  Here's what it says for the 5th week:
"The tiny embryo has a head and a tail end. By this time all the building blocks for the baby's vital organs are in place.The brain and spinal chord has already started to form.Tiny blood vessels are now forming.  The embryo is taking oxygen through the developing placenta and the bag of membrane (amniotic sac) is also forming. This will contain the water(amniotic fluid) in which our baby will be protected and continue to grow. At this stage, the developing heart can be seen as a bulge. The embryo would look like a prawn in shape. At this stage the head can already be distinguished clearly from the body.  The embryo has a curved back which marks the begining of the central nervous system. The embryo is attached by a stalk to the developing placenta".
