Progesterone is checked on "Day 21" of your menstrual cycle to confirm that ovulation has occurred. This is because progesterone levels rise following ovulation. A low 21 Day Progesterone level suggests that your cycle was anovulatory and no egg was produced. If no egg is produced, pregnancy cannot be achieved.
Progesterone at day 21 of your menstrual cycle.
Progesterone is a hormone produced mainly in the ovaries by the corpus luteum (what the follicle turns into after it releases the egg). Progesterone helps prepare the uterus for the implantation of a fertilized egg. If a fertilized egg implants, progesterone then helps the uterine lining (endometrium) to maintain the pregnancy.
Any woman trying to conceive, planning for the future or just curious about her fertility status.
This test must be taken 7 days before an expected period. This is Day 21 of a 28 day cycle. If your cycle is longer or shorter, you must adjust the day you take this test accordingly. For example, if your cycle is usually 35 days, you should take this test on day 28.
Fertility is decreased by half among women in their 30’s compared with women in their early 20’s.
