During a 28‑day menstrual cycle, the plasma estrogen concentration (in pg/mL) on successive days is recorded as follows: day 9 = 180, day 10 = 210, day 11 = 220, day 12 = 190. An LH surge is known to occur on the day after estrogen has been above \(200\) pg/mL for at least two consecutive days, and ovulation takes place about 36 hours after the LH surge.
