NoDoctor's answer:
Emergency contraception mainly has two types. One is mifepristone tablets, marketed as "Fernier." Its advantage is that only one tablet needs to be taken within 72 hours after sexual intercourse, with a contraceptive effectiveness of over 99%. Low-dose mifepristone is a new drug approved by the National Drug Administration in the early 21st century for emergency contraception. The other is levonorgestrel tablets, marketed as "Yuzhenting" and "Anting." Its feature is that two tablets need to be taken within 72 hours after sexual intercourse.
