NT Scan Done too early???

My OB did my NT scan too early (9 weeks 6 days) and said it appeared abnormal so sent me to a perinatologist. My husband and I were devastated but the perinatologist seemed optimistic and said she only saw the NT being 1.5 at 10 days and that I was perhaps measured too soon. We are now just waiting on our genetic testing results but the waiting is hard. I’m 37 and my husband is 41. This will be our first and it’s our little rainbow baby. We are just scared. Anyone have something like this happen?
