A 33 year old lady presents 6 days (144 hours) following unprotected sexual intercourse (UPSI). This was the first episode of UPSI in this cycle. She had been abroad at the time but has returned home and decided that she wants emergency contraception. She has regular periods and you calculate the earliest likely date of ovulation is 24 hours ago. She takes no medications and has no other medical conditions.
Which of these (if any) is the most suitable to use for emergency contraception?
