Quad screen blood test...dates....?

[dboo]

I am STILL confused about this. The Quad screen bloods cannt be done until the 15 week mark has been reached. The ultrasound (BPD) showed 15 weeks and that is the date the doc used. BUT that is IMPOSSIBLE! It had only been 14w1d since last LMP. I asked the doc and she said to believe the results but I still don't get it! Help.

if this helps in some way... you have to remember there is 2 weeks being the day of ovulation n day or period that is counted in pregnancy so if i am 19 weeks but my lmp dates really i am 17 weeks if u get me... So mayb the doc has taken that into consideration somehow... Realy i have no idea jsut thought it might helped...

Hmmm....no, that would make it even worse, at only 12w1d!
