What's the harm of taking an emergency contraceptive pill?

Taking an emergency contraceptive pill can cause menstrual disorders, dysmenorrhea, increased menstrual blood volume and other hazards. There are no other obvious hazards. Because contraceptives contain a lot of hormones, they can lead to severe endocrine disorders, which can cause infertility in severe cases. Therefore, you should prohibit relying on contraceptives for contraception.
