Correct answer: E — Wait 5 days before starting POP and use condoms after starting

Progestogen can reduce ulipristal's ability to delay ovulation, so hormonal contraception should be delayed for 5 days after UPA. After starting the POP, additional precautions are required until it becomes effective. Waiting until the next period is unnecessary and leaves a longer risk window.
