You are right, there is no shame in a woman taking care of herself. There is, however, shame in not taking care of her child. If a woman is not ready for motherhood, she should not have sex or only have sex while both her and her partner are using multiple forms of contraception.
I would never undermine a woman’s Right to Life, whether she is born or unborn. Expecting a mother not to kill her child does not affect her Right to Life. Not killing her son or daughter will not end her life.
