Question

I've been trying to conceive through ovulation timing for a year now. I was on Clomid for this month and my progesterone was checked after ovulation which was 17.1. I have a 31-34 day cycle.

Did the 17.1 level truly indicate pregnancy? What else could it indicate?

Priya

Answer

Dear Priya,

Your progesterone levels normally rise after ovulation. You do not say when this was taken relative to the timing of ovulation (early, mid, or late luteal phase), as they will vary during the postovulatory phase, but a level
of 17.1ng/ml can just indicate that you are postovulatory, and is not necessarily indicative of pregnancy. If pregnant, the progesterone levels will continue to rise, rather than fall as they will if you have not
conceived, precipitating the next menstrual flow.
