The baby has moved down into the pelvis and abdominal expansion becomes very pronounced. Some women experience temporary navel protrusion during this period. Pain in the upper leg joints and pubic bone becomes more intense.
As childbirth approaches, the vagina and opening to the uterus relax and vaginal discharge increases. Several times a day the abdomen will feel tight and swollen and there will be some pain.
Some women begin to experience something similar to labor pains, known as prelabor labor.
At 39 weeks, baby's weight is around 3,000 g and length about 50 cm.
The muscles around the mouth have developed sufficiently to enable the baby to breastfeed. By this stage, the baby is ready to be born at any time.
