Jesus fucking Christ, Grumpy...your words are right there.
What you said was, "There is no reason why a woman should have an unwanted pregnancy."
Man up.
Who the hell are you to think "I do not want to be pregnant" is NOT A VALID REASON?
Why do people like you think it is okay for you to make decisions of this sort for a pregnant woman?
Get off it.
Opposition to abortion is probably 99% religion motivated. Yeah, there are atheists and agnostics who oppose abortion for any reason...but the VAST MAJORITY of people who oppose it are motivated by religion. I do notice that since the religious objections are so shallow and easily defeated, most people who are anti-choice pretend it is a secular decision on their part.
Okay...hypocrisy is allowed.
If you are a woman who does not want to be pregnant...abortion is the MUCH better choice.
Anyway...you never actually answered the question.
If a woman makes a valid attempt to prevent pregnancy...or is impregnated by rape...are you saying it is okay for that woman to get an abortion?
