A woman with a regular 28‑day menstrual cycle measures her serum progesterone on two occasions: on day 20 the level is 2 ng mL⁻¹ and on day 22 it is 8 ng mL⁻¹. Ovulation is defined as the first day on which progesterone exceeds 5 ng mL⁻¹. Assuming progesterone rises linearly between the two measurements, on which calendar day of the cycle did ovulation most likely occur?
