How was your 20 wk u/s? When I went in for mine everything looked so great they advised me not to do the quad blood tests, they said it just causes more worries. There were no markers at all on the u/s and because of my age (I am only 31 and will be 32 when I deliver) but I guess even at my age the tests would come back with a higher risk. I am really leary anymore about all those early tests since so many women have had horrible early screening tests and did the amnio and everyone has come back that everything is normal. I really don't know about your situation, but I do know that often your due dates change alot by measurments, so it seems like maybe it is just a matter of your dates being diff and needing to wait and see how the baby keeps developing to get you a better idea of the exact due date before they really calculate your results. Best of luck to you!
I have recently heard that having your dates off can effect your quad test but im not positive. Do you know think the dating of the last U/S is right?? Sometimes babies are just smaller. There is an average size for babies but they come in all sizes:) If the quad came back normal for your origanal due date, hmmm IDK, im sorry:( Did they refer you to a genitic conselor?? I would definitly talk to one to help ease your mind. I have recently had to deal with this and I know how stressful it can be. Please keep us updated. You will be in my thoughts:)
