Correct answer: A — Hydatidiform mole

Hydatidiform mole is the best answer because the vignette is testing Molar pregnancy and the recommended approach is consistent with RCOG Green-top Guideline 38. The other diagnoses do not explain the combination of timing, examination findings and investigation results as well as the correct diagnosis. Specifically, Bacterial vaginosis; Pelvic inflammatory disease; Threatened miscarriage; Vulvovaginal candidiasis would be suboptimal in this scenario. The key discriminator is the pattern across symptoms, examination and timing, not a single isolated symptom.
