I'm mega-worried. Almost makes me long for the days when you were just pregnant until you had your baby. No scans, no tests, just the happy surprise at the end. And I know I could decline this test, but if there is something wrong, even something non-life-threatening like Downs Syndrome, I would rather know so we can prepare for a baby with special needs. I think it's pretty normal to want one's baby to be as healthy as possible, and I know that if this baby is Downs, it has been since the moment of conception - it's not because of something I have or haven't done. That's a big thing with me - maybe it's Catholic guilt.
Whatever happens, we'll always have the magical moment where we discovered we were having a baby. That we could. No one can take that away from us.
