Correct answer: A — Lactational mastitis

Lactational mastitis is the best answer because the vignette is testing Lactational mastitis and the recommended approach is consistent with NICE CKS Mastitis. The other diagnoses do not explain the combination of timing, examination findings and investigation results as well as the correct diagnosis. Specifically, Ectopic pregnancy; Vulvovaginal candidiasis; Threatened miscarriage; Bacterial vaginosis would be suboptimal in this scenario. The key discriminator is the pattern across symptoms, examination and timing, not a single isolated symptom.
