down syndrome screen positive

Hi everyone.. so my worst fear came true yesterday when I received my 2nd trimester screening results (quad test) and it came back 1/100 risk for downs . I wasn't quite willing to do the test as I knew the stress it brings with but did it anyway as per my dr advice and here I'm with these results. I know it could be false positive because I'm 35 yo but the anxiety has kicked in. I've lost my 6yo daughter to leukemia 2 yrs ago and then we were blessed with a baby boy who's 15 months old now. I can't deal with anymore stress in my life .I'm scared to go through invasive testing for risk of miscarriage plus I can't be on bed rest as I've to watch my baby 24/7 .plz give me some words of encouragement and share your experiences where you went on to have a normal healthy baby after positive screen .I'm waiting for my dr call yet because I received these results in my email as I've online account with the hospital patient portal. The anxiety is high .
