Contraceptives eat too much can lead to infertility

Emergency contraceptives are suitable for use within 72 hours after unprotected sex. The earlier they are taken, the earlier they can be used. However, the overall effective contraceptive effectiveness of emergency contraceptives is only about 80%, and the side effects are relatively large, such as irregular menstruation, headache, nausea, etc., which may not necessarily lead to female infertility. If there is no birth plan for the time being, condoms can be used for contraception.
