12weeks 1day, just got back from my nucual scan with good measurements but bloodwork showed super low free beta hcg (.5) and even lower papp-a (.1) which shows my risk of trisomy 13/18 as 1 in 30. They said it could just be the low levels trickling down so it sends that risk up and suggest I see their genetic specialist for more testing! So frustrated for paying soooo much for PGD and still have this as a risk. Nurse also said the blood test doesn't take into consideration that I already the PGD ....but it shouldn't it's it's own test giving me this info. Just venting...was going to announce this pregnancy as my son's first birthday party next week, now hubby and I are a little iffy. Grrrrr!
