If it is a short-acting oral contraceptive pill used for regular contraception, it will not affect future pregnancy and will not cause infertility in the future because the dose of progestin contained in the pill is relatively safe and small, and can be used normally as long as hormonal contraindications are excluded and liver and kidney functions are normal. If the emergency contraceptive pill is used as a remedy, it may lead to infertility in the future because the dose of progestin in the emergency contraceptive pill is relatively large, equivalent to the dose of short-acting oral contraceptives for eight days, and cannot be taken orally more than three times in a year. If used excessively, it may affect the menstrual cycle, affect ovulation, and even affect future pregnancies, and in the most serious cases, it may affect ovarian function.
