blood test - which is best CD 2 3 or 4?

[cazd]

Hi girls, I've got to go in for my CD-specific blood tests but I wondered if you had any advice on which day is the best?

I can go any time - does it matter at all which day I choose - or would you recommend one over day over the others?

Thanks!

It depends what they are testing I think FSH is cd3 and progesterone is cd21 ( although its really 7dpo).

Is that what you mean?

Hi Caz,
My doctor does the test on cd2 (for fsh and estradiol, right?), but I've heard of others doing it cd3. I happened to be going for my first appointment to the FS on cd4 and they took my blood but said that the levels could be falsely elevated because it's a little later. In the end they were the same as when I did it a month later on cd2 so I don't think it matters a whole lot, but I think cd2 or 3 would be safest. Hope that helps!
