NT is more than 3mm

hi mummies, has anyone ever been told that their baby NT is more than 3mm, and were told that baby might have a risk of down syndrome or any other abnormalities? i went for my checkup and did my scan and were told the bad news. didnt want to do any down syndrome test so i have to wait for 18 weeks to see how it goes. has anyone experienced this? i cannot stop thinking. couldn't stop crying either. and this is my second pregnancy.
