[|AI|]  Hello, Thanks for sharing your health concern with us. I have gone through your query and would like to offer my opinion. The efficacy rate of an emergency contraceptive pill depends on the time delay after the intercourse before the pill is used. When the pill is used soon after, the protection offered is 98-99 % while it decreases as time goes by. At 60 hours, the protection offered is around 80-85 %. Corvette is shown to have the same efficacy as any conventional emergency contraceptive pill. Please contact your health care provider for further help. Hope this helps.
