Day 21 Testing. On Day 21 of your cycle, your fertility specialist may want to check the levels of progesterone and estradiol (E2) in your system and the thickness of your endometrium (uterine lining). Day 21 testing checks a womanâs progesterone level to confirm that ovulation has occurred. It is done on the 21st day of the menstrual cycle (Day 1 is the first day of flow, not including any spotting). A low Day 21 progesterone level suggests the cycle was anovulatory (no egg was produced).
