Hi! I think I've replied to one of your posts before (not sure though!) My 15mo old has down syndrome. I'm 23 years old and so is my husband. I'm due next month with baby boy #2, who is genetically fine.
The bloodwork and NT measurement only indicate a percentage of chances, BUT neither is really accurate.
Here's the link to my Journal here on MH regarding down syndrome risks and new parents:
A person doesn't have to have a history of DS in their family to have a child with it. Even though women over 35 are at a higher risk for a baby with Trisome 21, %80 are born to moms UNDER 35 since we have more kids. Feel free to send me a private message with any questions you think I may be able to answer.
I'm not a doctor BUT I have a love of anything medically speaking, and when we found out TJ has down syndrome (at 17w pregnant following Amnio test) I did tons of research, so that's where i get my knowledge. :)
