[|AI|]  Hello, Thanks for letting us know your health concern. The emergency contraceptive pill provides high protection when used soon after the unprotected intercourse, within 6-12 hours. The effect however, stays until 4-5 days as shown by half-life studies. Moreover, presuming she has regular monthly periods, she is in her safe period. Ovulation occurs two weeks prior to the onset of the next cycle and this is the fertile phase. So, she did not need the pill in the first place; and another pill is not necessary. In the future, please choose regular contraception as the emergency contraceptive pill can cause hormone imbalances. Hope this helps.
