progesterone level

i have to do serum progesterone level at day 21 of my cycle . last period start from 3,march so the best day to do the test will be at 23 or 24 march ? and does it matter to be exactly at these dates and what is the normal range for the hormon at this time ?
thx

Ideally you want it 7 days after ovulation, 5-9 days is the range.  I believe a level of 10 or above is what is looked for.  Anything over 2 indicates you have ovulated.

7-9 dpo is the time progesterone is at its peak...

i am so confused...i am new to all of this clomid, testing, counting, and the such.  I had a color change on my ovulation kit.  I went to the doctor today and my serum progesterone test came back as a 33!  My doctor's office said to wait until next Tuesday to see if i'll menstrate or to check for pregnancy.  I am clueless!!!

I'm in with you. I had my progesterone level tested today which is cd 24 and 7dpo. Mine came back at 43.6! I'm so excited! She told me i can do a hpt on saturday and then wait til af shows (which she wont ;) or having ablood test next wednesday.  this week is gonna take forever1

33 is a good number, as is 43.6.

See other note on foreverpoppy's thread about what the progesterone is doing for ya'll.  I copied some info off wikipedia so that I wouldn't get it wrong.  Basically, progesterone sets up the environment and is then generated by the placenta. You want good numbers, and if they stay high...then the probability of pregnancy is high (so around the time of menstration, if your progesterone doesn't drop, you won't menstruate).

Keep the faith, maybe you both will have good news soon.
