I am STILL confused about this. The Quad screen bloods cannt be done until the 15 week mark has been reached according to my clinic. 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.
