The same way your body has been working overtime, your baby’s organs are keeping themselves just as busy during the last week of the first trimester. The liver secretes bile, the pancreas produces insulin, and the kidneys form the urine to transport residue to the amniotic liquid. The intestines, which resided partially in the umbilical cord, are entirely inside the abdomen, now that there’s enough space for them. Throughout the next couple of months, the body will grow at an incredible pace to follow the development of its head. At the moment, your baby is the size of a pea pod.
