Patient's question:
Will taking emergency contraception cause menstrual cycles to decrease or amenorrhea?Doctor's answer:
Hello, taking emergency contraception pills can cause menstrual disorders. Emergency contraception pills contain high levels of estrogen, and the dosage for one emergency use is equivalent to 8 days of regular short-term oral contraceptive pills. Excessive dosage can lead to gastrointestinal discomfort, menstrual cycle irregularities, ovary suppression, and other phenomena, disrupting the normal menstrual cycle and causing endocrine disorders. If taken for a long time, severe cases may result in amenorrhea. This can affect ovulation, thereby impacting fertility. Generally, no more than 3 pills should be taken in a year.
