The blood test we had done last week after we were notified of the soft marker for Trisomy 18 has come back negative. Which means "normal" and that puts our risk level back to about 1/1200. I can live with those odds
Such a huge sigh of relief to have the results back. We will still go back for the second anatomy scan at the end of June to check if the cyst has gone away but for now I can stop worrying about T18 and move onto something else (I am sure there will be lots more worrying in the next 20 weeks).
Thank you for all the thoughts, prayers and reassuring words.
