According to the public health network, taking emergency contraception three times a week is an excessive and frequent behavior, which is easy to reduce the contraceptive effect, and can also lead to endocrine disorders, menstrual disorders, irregular vaginal bleeding, and even lead to infertility in severe cases. Emergency contraceptives, also known as morning-after contraceptives, refer to drugs used for contraception when contraceptive measures are not taken in time or fail.
