The emergency contraceptive pill can be taken orally after intercourse and will be 80% effective, so it works better. However, if you want to take short-acting contraceptive pills orally, there is no effect, because short-acting contraceptive pills need to be taken orally for 7 days in a row to achieve 99% contraceptive effect, so if you do not want to conceive, you should still take emergency contraceptive pills orally. If possible, the emergency contraceptive pill should be taken 12 days after the oral dose and tested with an early pregnancy test to rule out the possibility of conception, because the emergency contraceptive pill is not 100% contraceptive. If the pill is successful, the result will be negative, which means there is no conception, so you can wait patiently for your period. In the future, as far as possible, you should take condoms for contraception, too many times of oral emergency contraceptive drugs will cause menstrual irregularities, but also affect the endocrine hormones in the body to produce certain changes.
