Does a Birth Control Pill Kill a Fertilized Egg?
The birth control pill prevents the pregnancy in three ways: (a) The pill thickens the cervical mucus to make a difficult pathway for the sperm to reach the egg; (b) This suppresses the ovulation by mimicking the pregnancy-level hormones in the body and prevents the release of eggs from the ovaries; (c) The pill makes the lining of uterus inhospitable for any fertilized egg reaching it.
