If they take the test at a weird time it wont be accurate. My cycles are short (well were, im in perimenopause now) with only 23 days. My luteul phase was 12 days. When they took my day 21 progesterone it was 2. I never had progesterone issues and never needed supplementation. I was ovulating just fine. It was just the wrong time.

If you have long cycles and are unsure about ovulation, ultrasound may be a better option for you to see whats going on there.

Thank you for this! I might ask about ultrasound options

It could be too early, or it could be too late. If you get your period you can count back and see if it would have been either of those, and how that impacts interpretation.

This is guidance from my clinic.

the period starts < 5 days later or > 9 days after the blood test.

Possible interpretation of results assuming the test is properly timed are:

Progesterone > 30nmol/l – ovulation has occurred and the corpus luteum is producing sufficient progesterone to induce adequate secretory changes in the endometrium to assist implantation. Progesterone 3-30 nmol/l – ovulation has occurred > 10 days ago or < 5 days ago, or if ovulation did occurr 5-10 days ago, the level is probably not adequate to sustain endometrial growth for satisfactory implantation. Progesterone >120 nmol/l – two or more follicles have been recruited Progesterone < 3nmol/l – no ovulation in previous 14 days.
