Making abortion illegal is not going to appreciably change your scenario.  If someone feels they need an abortion, or are told they will have an abortion,  it usually happens one way or another.

Sometimes the best intentions do not work out well at all.  One example is parental permission laws.  In your scenario had your parents wanted you to have an abortion you would have had no choice.  I know a young lady in my area whose father was insisting on an abortion, but she did not want it.  My State has no parental permission laws.  The Planned Parenthood clinic her father took her to, insisted she had the right and the legal standing to make the choice to have the child.  Her father was incensed but her decision was respected.  That boy is now 10 years old and grandpa loves him dearly.   Pro choice is just that, pro choice....no matter the choice.
