Fear of pregnancy can be remedied by taking oral emergency contraceptive pills. Emergency contraceptive pills can be taken within 72 hours after unprotected sex, but they can also be taken within 5 days after sex. These are two different types of emergency contraceptive pills, including levonorgestrel and mifepristone. Generally the earlier the emergency contraceptive pill is taken, the better the contraceptive effect, but it is not 100% contraceptive. After taking emergency contraceptive pills, if there is a lack of menstruation or repeated small amounts of vaginal bleeding, it is recommended to go to the hospital to determine if you are pregnant. Emergency contraceptive pills are not recommended to be taken for a long period of time and in large quantities, so as not to affect the body’s endocrine system. For those who do not want to have children, it is recommended to take effective contraceptive measures, such as condoms and birth control rings.
