According to the search results, the chances of getting pregnant without protection but pulling out are not zero. The effectiveness of the pull-out method varies depending on how well it is performed. If done perfectly every time, it can be relatively effective, with only 4 out of 100 people getting pregnant. However, in real life, it can be difficult to do it perfectly, and about 22 out of 100 people who use withdrawal get pregnant every year, which is about 1 in 5. The pull-out method is about 80% effective. The method does not protect against sexually transmitted infections (STIs) . It is important to note that pre-ejaculate can contain sperm, and it only takes one sperm to cause pregnancy. Therefore, even if the man pulls out before ejaculation, there is still a risk of pregnancy. It is recommended to use other forms of birth control, such as condoms or birth control pills, for added protection. Emergency contraception, also known as the morning-after pill, can be used if semen gets in or near the vagina. It is also important to keep in mind that the chances of getting pregnant increase during ovulation, but it is still possible to get pregnant at other times of the menstrual cycle.
