I am really so exhausted and so angry that a positive free beta screen has taken away all the joy I was feeling. I am 40 and am due in November. I have two sons 5 and 4. During my previous pregancies I never took any blood screening tests because of the false positive results and opted for this really great u/s where this really nice doctor looked at my sons and said they look great. This time they didn't give me an option they made me take a new and improved blood test with less risk of false positive results. The u/s was lovely with no additional n/t fluid behind the neck --we were almost giddy. They marched us into the Geneticist's office for what we thought would be improved stats. Instead, they told us sorry they blood results were "less promising than the u/s" now our odds went from 1/60 to 1/28 chance of a baby with ds. As before, my husband and I will have and love this baby no matter what. I just can't help obsessing over it and feeling guilty that I may have done this to a child when I already had so much. (I know that sounds awful) I spend hours I don't have on the internet looking up obscure articles about the presence or abscence of a nasal bone and then starring at my baby's profile trying to see if it has one. I am scheduled for an amnio next week but I am calling it off on Mon. I was told the stats are 1/200 for m/c at this stage. Which means that in addition to really ailing parents and a job that is just oozing in stress I will worry and not sleep until the 20 week u/s which may not give us any more information.
