How many times can the 72-hour contraceptive pill work?

Nowadays, many young couples do not know how to take contraceptive measures for the sake of passion, which has a great impact on the physical health of female friends, especially taking contraceptive pills afterwards, which will affect pregnant women and cause menstrual disorders and infertility. Under normal circumstances, the best time to take birth control pills is within 24 hours after sex, and you cannot take birth control pills twice within 72 hours, as this will seriously harm women's health. I hope this will attract attention.

Each contraceptive pill has a different way of taking it. Although the contraceptive pill lasts for 72 hours, it is usually only effective before intercourse, so you may still get pregnant if you have intercourse on the third morning. In addition, if it is the ovulation period, the chance of pregnancy will be higher, and the contraceptive pill may be ineffective even if taken afterwards.

Most 72-hour contraceptive pills refer to emergency contraceptive pills, and the most commonly used one is Yuting. The 72-hour contraceptive pill cannot be used repeatedly. It is effective if used within 72 hours after unprotected sexual intercourse. Generally, it only works for this one sexual intercourse. After taking it, contraceptive measures should be taken until the next menstruation. After healthy women of childbearing age have ruled out pregnancy, the drug should be used within 72-120 hours after sexual intercourse. The earlier it is taken, the better the effect. The failure rate is often higher if it is taken more than 72 hours. Do not take it more than 3 times a year, otherwise it will cause habitual miscarriage.

Emergency contraceptive pills do not protect against sexual intercourse after taking them, and pregnancy is still possible. Because emergency contraceptive pills are emergency pills, they are only effective for the previous sexual intercourse and have no protective effect on the next sexual intercourse, or the protective effect is very small. If you are not sure that you do not want to get pregnant, it is recommended that you take the emergency contraceptive pill again to avoid unnecessary trouble. Taking emergency contraceptive pills can cause menstrual disorders. It is best not to take this medicine frequently. This type of emergency contraceptive pill has great side effects, and menstruation will either be advanced or delayed.
