Pregnancy doesn’t have much to do with whether or not you go to the restroom after intercourse and expel the semen. This is because when the sperm and the egg combine, it can and does happen in a split second. Because it is not possible to completely expel the semen when you go to the toilet, there may also be a chance of pregnancy at this time. It is just that it may be reduced in this way, but it cannot be said that you will not get pregnant for sure. If you are not planning to conceive or get pregnant, you may choose to take emergency contraceptive pills by mouth if possible to prevent pregnancy. Emergency contraceptive pills should be taken on an empty stomach or 2 hours after a meal, and will be about 80% effective. You can buy a pregnancy test about 12 days after intercourse to rule out the possibility of pregnancy. In the future, if you are not planning to get pregnant, you should use contraceptives as much as possible.
