My son was born in 2013 at 27 weeks gestation for unknown reasons. It was a long road but he's now a happy and very healthy 3 year old. It took quite awhile for us to feel ready to try for another baby. I had two early miscarriages this past year, one in August and one in November. I'm currently at 12 weeks and just got the call that my Materniti 21 came back positive for Trisomy 18. I'm devastated. I'm 38 so we knew that my age, plus my history of preterm delivery, made it high risk, but I didn't expect this. My doctor has stressed that its a screening test, not diagnostic, and there is a possibility that the abnormality is confined to the placenta. I've done a little research in the short time since I got the news and, although false positives are possible, it doesn't appear likely. Has anyone has any experience with this, good or bad? We hadn't told anyone about the pregnancy yet and I was just hoping for a little support, and maybe hope.
