Correct answer: C — Mid-luteal progesterone about 7 days before expected period

Mid-luteal progesterone about 7 days before expected period is the best answer because the vignette is testing Ovulation confirmation and the recommended approach is consistent with NICE CG156. The other tests may be useful in different pathways, but they would not be the most direct first investigation for this presentation. Specifically, Newborn bilirubin measurement; Transvaginal ultrasound scan; Pelvic ultrasound; Advise trying to conceive for another two years would be suboptimal in this scenario. The first investigation should answer the immediate clinical question and follow the relevant UK pathway.
