Why do you get pregnant even after taking birth control?

Patient's question:

Why do people get pregnant even after taking birth control, I mean under no contraception measures, immediately taking the medication, I don't understand. First, the medication is not a fake drug, so why

Doctor's answer:

Hello, if contraception fails after taking birth control pills, continuing the pregnancy still carries risks. If you choose to have another abortion, it may also be harmful. Multiple abortions can increase the risk of infertility, habitual miscarriage, and other complications. It is important to carefully consider your decision. If you still plan to keep the child, it is necessary to undergo regular prenatal check-ups.
