pregnancy

I am 15 weeks pregnant with twins. I had Nuchal ultrasound and have low risk of Down syndrome. The results showed (1.4, 2.1 thickness of the back of the neck) How low is my risk? question 2: I occasionally have alcohol, how damaging a few drops of Brandy or wine can be to the foetus? Thanks Nilli

Dear Nilli every result below 3 mm. is good, did you do also a blood test ? because the better result is combining both ultrasound and a blood test regarding the alcohol,it's not that damaging in these quantities, but it's better off without it during pregnancy good luck Gili
