Baby development at week 41
Going past your due date is common, especially for first pregnancies, and is medically normal up to a point. The baby keeps growing slowly and the skin may dry or peel a little as the vernix has mostly gone. Your provider will likely step up monitoring of the baby's heart rate and the amniotic fluid.

The third trimester (weeks 28–40+) is about growth and getting ready for birth. Prenatal visits become more frequent, the baby gains most of its weight, and you'll watch for the signs of labour. Tiredness and physical discomfort tend to return as the due date approaches.
