Birth-control may be necessary for the sake of the mothers health. What if the doctor says that she cannot have more children?

The Catholic Answers

Doctors are not infallible, and irreligious doctors are often only too ready to please women by telling them that they are unable to fulfill the duties of motherhood. And as a matter of fact contraception normally has a worse effect upon a woman’s health than childbirth. She becomes a neurasthenic wreck in the end. But in any case, since contraception is evil of its very nature, no earthly consideration can justify it.
