21 day blood test opinions please

[Dee28]

So i'm due to have my 21 day blood test this month and CD21 is Friday. However i didn't ovulate until at least CD18 (possibly 19) making day 21 only 2 or 3dpo. I understand that its called a 21 day blood test based on an average 28 day cycle and that progesterone peaks around 7 days after you ovulate and thats why the test is done then. So my question is should i go ahead and do it tomorrow and risk a low result that may stress me and may not be totally accurate, or should i have it done next Tuesday which will be CD25 but around 7 dpo for me? I'm thinking I should wait til next tuesday to get a more accurate result. I don't temp but i do opks and had smileys monday afternoon and tuesday morning. Thanks xx

^^wss. I always assumed they took into account not everyone ov's on the same day but it's worth checking x

i'll just have to go to my local hospital and sit and wai for the blood test so they won't know, they just take what the form says. I did think about calling the GP but she was so vague about the whole thing when i asked for the blood test that i don't think she would be as knowledgable as i want her to be if you know what i mean!

I'm not sure waiting to ask tomorrow will be of any help, it's usually just a phlebotomist taking the bloods so they won't have a clue. Ring your GP and ask xx
