The water in the amniotic sac is a protective substance that protects the baby from infection and it acts as a cushion to protect the baby from injury.
There also can be slight leakage of amniotic fluid or minimal blood loss, but providing that the woman rests for a few hours afterwards and avoids strenuous activity for 24 hours afterwards, this can be kept to a minimum.
