Principles of taking birth control pills after ovulation

If you want to avoid pregnancy, women can choose to take birth control pills after sex. There are many types of birth control pills, including oral contraceptive pills, topical contraceptive pills, and period contraceptive methods. Among them, oral contraceptive pills are the most commonly used method.

Oral contraceptives work by preventing sperm from combining with eggs to prevent pregnancy. When a woman takes oral contraceptive pills after sex, the drug enters the body and prevents sperm from combining with the egg. In this way, even if a man successfully fertilizes, oral contraceptives will prevent the fertilized egg from implanting, thus preventing pregnancy.

However, oral contraceptive pills are not 100% safe. Although most oral contraceptive pills have a high success rate, failure can still occur. If oral contraceptive pills fail, a woman will need to have an abortion.
