Like most pregnant women, you are probably looking in the mirror every day for your baby bump. However you will not have an obvious bump until the fourth month. On average, the fourth month of your pregnancy marks the greatest period of growth, with your pregnancy most definitely appearing as a rounded abdomen. In the mean time, you may currently be feeling the urge to urinate more frequently. This is because more blood is being pumped through your kidneys so you are producing more urine. Also, as your uterus grows, it puts more pressure on your bladder, which can give the sensation of having to urinate more frequently..

This week your baby’s vital organs, including the lungs and gut, start to develop. Your baby’s head already looks too big for his body as the brain rapidly enlarges. Your baby’s lungs won’t be fully developed until late in pregnancy, but the foundations are being laid down right now. Lung development begins with a small lung bud branching out from the upper part of the tube between your baby’s mouth and stomach, which is the esophagus. This bud will form the trachea, which then forms a right and left branch, which will form the lungs. Completion of lung development will not occur until later in your pregnancy.

What will become your baby’s arms and legs are also starting to develop in the seventh week of your pregnancy. At the end of the seventh week, there are four simple limb buds, each slightly flattened at the end where over the next two weeks, a hand or foot will form. Upper limb development will occur before lower limb development. On your baby’s face, eyes are also beginning to form. The eyes are the first recognizable landmarks to form on the face. The eyes will consist of two dimple surface indentations, which then develop a second indentation within the first.
