Progesterone levels (produced from the corpus luteum) peak 7 days prior to the onset of menses. If a menstrual cycles is regular and conforms to a standard 28 day length, progesterone concentrations will normally peak on approximately day 21 of the cycle (with day 1 being the first day of menstruation). Therefore, when assessing for ovulation, progesterone should be measured at day 21 of the cycle or 7 days prior to the expected onset of menses. If a woman has an irregular or prolonged cycle then progesterone can be measured on a weekly basis until the onset of menses.
