Could be either time: Since the emergency contraceptives are only 95% effective if taken within the first 24 hours after unprotected intercourse and does cause irregular bleeding and conception is possible at pretty much any time in the cycle you could have possibly conceived either time. An ultrasound for dating will tell you which is most probable. Hope this helps.
