1:160 odds

So I really think the nurse practitioner I have is useless. I found out today that my odds for having a baby with ds are 1:160. That's really freaking good! Plus the comment from the lab was "lower risk for ds than based on age alone" which is also really very good. That means normally a 40 year old woman has a 1:65 chance of having a baby with ds. This was  good news today.
