Taking the emergency contraceptive pill twice a month can be very harmful to the body. Because the amount of estrogen and progesterone in the emergency contraceptive pill is relatively large, one emergency contraceptive pill is equivalent to eight ordinary contraceptive pills, and taking the pill twice can cause menstrual disorders, early menstruation, irregular vaginal bleeding, and in some cases, amenorrhea due to taking the emergency contraceptive pill. Therefore, the emergency contraceptive pill is only meant to be taken once as a remedial measure when having unprotected sex near ovulation, and should never be used as a regular contraceptive measure. Emergency contraceptive pills should not be taken more than three times a year, and frequent use can cause endocrine hormone secretion disorders and affect ovulation. Therefore, the emergency contraceptive pill should be taken very carefully afterwards, only to observe to see the menstrual situation, if there are problems in time to go to the hospital for examination.
