Odds

So after the NT screening, I had my first blood drawn checking for birth defects. I got a call back from the clinic today telling me that the odds for my baby to have Downs are 1 in 2500 (which is good consider with my age it's 1 in 381, that's a big improvement). And the odds for the baby to have Trisomy 18 defect is 1 in 10000. She said that it's the lowest risk factor they give out. I'll have to have a second blood drawn in a few weeks to check for some other chemicals in it to get a higher accuracy. But so far the odds are looking pretty good.
