At present, the more widely used emergency contraceptive pill is Yutin, after intercourse, within 72 hours of oral Yutin, can achieve the effect of contraception. However, Yutin also has side effects, such as withdrawal bleeding after stopping the pill, which can even lead to menstrual disorders. Therefore, it is not recommended to take oral contraceptives except as a last resort. If you are not planning to get pregnant in the short term, it is recommended to use condoms, which are simple, convenient, safe, and effective. If there is no planned pregnancy for 2 years, it is better to get an IUD, which is acceptable to both spouses and has a good contraceptive effect.
