Has anyone had any day 21 blood tests done to measure progesterone levels? What were your results and what is the normal level?

Appreciate any help :-) x

I've got mine tomorrow.....feeling a little nervous! When will I be able to find out results?

You also need to sure to get the test on the correct day - as simple as that sounds! Day21 is based upon a typical 28 day cycle which most people don't have. But in theory you should be getting the test about 7 days before you expect your next period.
I've had the test done twice and both on CD23 because although I do have 28 day cycles, my CD21 is always a Saturday. My first test result was a 29 and not sure of the second as not been back to the GP for her to tell me but it can be quite a fiddly test to have.
Hope that's helpful.

Anything above 30 confirms ovulation.
