My cycle is 30 days(give or take), does this mean that I should actually have the blood test on cd 21 or cd 23? Also, do you know what they test for?

my cycle is between 28-32 days, and i have always tested on day 21, they are testing to see if you have ovulated

Thanks Kazzle
Just phoned the dr and he confirmed 21 days. Does anybody know why 21 days rather than 7 days past ov? It just seems a bit strange to me.
BTW - I spoke to the nurse who asked the dr so did not have the chance to ask him personally.

its day 21 from the start of your cycle, and thats because most ppl ovulate on day 14, so just because your cycle is about 30days, doesnt mean you ovulate later.....
i still ovulate between day 12-14 even though i can have 32 day cycles.....hope this helps

hi mummymegs, I have had three of these blood tests, and they do the blood test on cycle day 21 and it is to test for progesterone which is a hormone and the levels of it in our bodies rises after ovulation and it tells them whether you have ovulated prior to cycle day 21, but I don't think it tells them what day you ovulated, just whether it is likely that you have or not . Hopefully that makes sense to you lol

I have cycles of 31-37 days. I do not ovulate before CD21... my last 2 cycles I ovulated on CD25 and CD23, I am at CD23 today and have not yet ovulated.
Most people have ovulated by CD21 which is why they test then.

my specialist has given me bloods for the 30th wchich is CD27. he estimates OV for monday CD20 so couldnt he still do CD 21? or is he being on the safe side.
does it matter how many days post-OV you are when they get done, like does it change the result?

He could still give you day 21 bloods but they wouldnt show a decent level of progesterone if you hadn't ovulated yet, they'd only come up as 'possibly ovulated'.
Your progesterone rises over the 7 DPO and peaks on the 7th day, then slowly drops down again if you aren't preg and once it has dropped low enough AF will arrive.
Your best bet is to get them done at 7 DPO (or a day either side if you can't do it at 7 DPO) to avoid disappointment and for more accurate results to go off.
ETA: Just thought give you an example, last cycle I ovulated on day 18, I had a blood test on day 20 cos I couldn't make it on day 21, it came back as a progesterone level of 9 (so possibly ovulated), I had another blood test done day 25 (7 DPO) and the results came back as 69 (That was on 150mgs of Clomid)
Good luck

ahh, that makes heaps of sense. looks like the date he gave me will be perfect then :D i feel sorry for tee though cos she sits on my knee while i get them done cos i cant get a baby sitter as i have them so often with other things as well, she no longer has a fear of needles though. lol

I got a level of 3 which sounds very low to me. Anybody got any information about this and what my level should be?

I'm really worried that I'm not ov-ing seeing that the progesterone level should be over 10

Well if you got yours done on day 21, you would have only been 2 DPO so maybe it was too soon? I'm getting mine done today even though I'm CD26, because I ovulate a bit later too.
I agree that CD21 bloods are supposed to be done a week after ovulation and are only called that because you are "supposed" to ovulate on CD14.

I reckon that I ov-ed on cd16. FF may just be confused as I only recently started temping.
The dr wants to see me so have made an appointment for this afternoon. I still think that level 3 is really low for 5dpo because it would need to be above 10. crappy!

hi mummymegs, funnily enough I thought I had posted a similiar topic a while ago, and I just bumped it up for you, it just might help in understanding the levels a bit better. I know I found them quite confusing to begin with lol

On the 21 day progesterone front, I have to re-do the test and do a cd3 day test. This time the 21 day test must be done, wait for it, 7 days after ov. The dr has also asked me to temp from now on. He reckons it is the best method.

Mummymegs, I think I mentioned this before.
My 21's came back is 0.5 and we conceived. Its all about timing and not everyone fits into the mould.
The temping will help you see when you should be testing your prog.
