Correct answer: D — Discuss ulipristal acetate, noting oral EC may be less effective at higher weight

Higher body weight may reduce oral emergency contraception effectiveness, and ulipristal is generally preferred over standard-dose levonorgestrel when a copper IUD is declined and no contraindication exists. Pregnancy is not inevitable, so oral EC should still be offered after counselling. Waiting without EC misses the treatment window. Follow-up pregnancy testing is still advised if the next period is late or abnormal.
