For the most part, I suggest that expectant ladies keep the child, or give it up for adoption. It is so that they will never have to face grief and regret over death. Also, even though the baby belongs to the mother, he or she is still independent from her.
Obviously, if the pregnancy poses a danger for the mother, she can then have the procedure. Also, there is the case where if she thinks pregnancy would disturb her too much, such as a result of forced sex, then she could consider abortion.
I know some may not want a child, but are wise to be patient, before departing from it once it is born. There is the possibility that she may change her mind, and may want to take care of it.
I do speak of this issue, even though childbirth will be nonexistent someday, because it is a relevant one that pertains to everyday society.
