Hi I Recently Has My 12 Weeks Screening Done And

Hi

I recently has my 12 weeks screening done and the bloods have come back with my free BHCG being .32 mom . I have been referred on for further advice and the increased risk of trisonomy 13 is now 1:265... It doesn't have my actually beta reading. I'm so worried and confused- please advise on the .32 likely hood of trisonomy
