Does withdrawal also cause pregnancy?

Patient's question:

Hello! I would like to ask if withdrawal during intercourse can also lead to pregnancy? I am currently experiencing symptoms where my period is delayed by 9 days and has not arrived yet. I am really worried it might be a pregnancy. Additionally, I have been feeling bloated, uncomfortable, and experiencing stomach pain recently, compounded by a cold. I would like to know if it’s possible that I could be pregnant. Please reply as soon as possible! Thank you

Doctor's answer:

Ejaculation outside the body can also lead to pregnancy, as pre-ejaculate fluid is often released before ejaculation, which contains a small amount of sperm. It is recommended to take proper contraceptive measures and not rely on withdrawal as a method of contraception, as it is not reliable. If your period is delayed by more than seven days, it is advisable to use a pregnancy test.
