Unfortunately, you are wrong about this assumption. Many women definitely keep abortion in the back of their mind as a backup plan in the event they get swept up in the moment or if their birth control fails.
Here are just a few alternatives to slaughtering a living human being…
Abstinence
Emergency Contraceptive
Birth Control Pills
Female Condom
Cervical Cap
Fertility Awareness Method
Condoms
Injectable Contraception
Contraceptive Film
Intrauterine Contraception
Contraceptive Foam
The Patch
Contraceptive Implant
The Ring
Contraceptive Sponge
The Shield
Contraceptive Suppositories
Withdrawal
Diaphragm
Of course, I only approve of the non-abortifacient versions of these solutions.
