The emergency contraceptive pill is not 100% contraceptive in the first place, the chance of success is 80% and there is a 20% chance of failure. Therefore, if you take the emergency contraceptive pill, there is still a chance that it will cause pregnancy, but the chance of success is generally higher. If you are worried about pregnancy, you can go to a pharmacy and buy a morning pregnancy test about 12 days after intercourse to rule out the possibility of conception. You can also go to the hospital to have a blood test for human chorionic gonadotropin about 8 days after intercourse, as long as the value is below 5U/L, which is within the normal range, it means there is no pregnancy. Assuming that the oral emergency contraceptive pill has caused the pregnancy, from a eugenic point of view, this is the time to choose to terminate the pregnancy. There will be two ways to terminate the pregnancy, one is a medication abortion; the other is an induced abortion. Abortion can be performed as long as it is within 49 days, and abortion needs to be within 42-60 days, of course the earlier the better.
