basically, my sister was told this morning that her baby has chromosome 18.
It was apparently written as a small note on the bottom of her NT scan that her baby has it, but her risk factor for it was very small.
She had her morphology scan done 2 weeks ago and everything was apparently fine. She is having a girl.
She went to the maternity ward early this morning after having cramps most of last night and it was there that the GP/OBGYN told her that this is what her baby has and she is going into labour with what will be a stillborn baby due to chromosome 18.

She also told her that babies with chromosome 18 issues usually appear fine in the morphology scan but die and come out stillborn and that they won't know anything more until the baby is born.

Because she is 21 almost 22 weeks, she was told she is too far along for amnio and obviously way too far along for CVS. A different GP/OBGYN told her that the baby looks perfectly fine in the morphology scan, as did the sonographer (not that they would really say anything, anyway.)

It's just so confusing. My sister is absolutely beside herself with worry.
