THE 40TH PREGNANCY WEEK

Your amniotic sac now contains progressively less amniotic fluid; the birth is not far off.

Many women notice what is known as the "nesting instinct" during this time. This sudden burst of energy encourages you to be active and prepare your surroundings for the arrival of the baby. Many specialists believe that this behaviour naturally triggers contractions. Others in turn recommend that you do not take advantage of this burst of energy, but instead save your strength for the coming birth. 

At the end of your pregnancy, the baby is roughly the size of a watermelon.
