Correct answer: D — Delay POP for 5 days and use condoms meanwhile

Progestogens may reduce ulipristal’s emergency contraceptive effect, so starting POP should be delayed for 5 days. Immediate start is correct after LNG EC, not UPA. Condoms are needed during the delay and after starting until protection is established.
