was tested for DS and Trisomy 18 today as my partner lost a brother at 3 days old to Trisomy 18 and it has been known to run genetically in the male side of the family. We wrote our baby a letter each. We are so scared. He held his brother as he died. I'm terrified to think how he will cope if the test comes back positive. The next 2 weeks of waiting are going to be the worst 2 weeks of my pregnancy
