What many people are unaware of is that quite a few forms of birth control can actually kill a fertilized egg. Life begins at conception, that is, the moment the sperm meets the egg. This is not only biblical (which is our final authority), but has also been confirmed by science.
Many types of birth control work in more than one way. While they can halt fertilization before it takes place by either preventing ovulation or thickening the cervical mucus to prevent the sperm from meeting the egg, most forms of birth control have a “back-up” system that will actually prevent a fertilized egg from implanting in the uterus by thinning out the lining of the uterus, causing the death of a living human being.
Further, most contraceptive implants or intrauterine devices also work this way by preventing the implantation of a fertilized egg. It is very important that you understand every possible way your contraceptive works before using it.
