Progesterone tests on day 21, I thought 22 or 23 is fine too.?

Question

I see everyone saying you test for progesterone on day 21 to see if you ovulated, but my dr said either day 21, 22, or 23....has anyone else dr said that?

Answer 1

It isn't called a day 21 prog test anymore--it's now a 7days past ovulation test. The test is only valid 7dpo!
