First trimester screening

Hi everyone, today I am 13 weeks so I should be excited that I have made it to the second trimester! Unfortunately I received the news that my FTS results were positive for Down’s syndrome. 1 in 264 risk. I know there is still a good chance everything is okay, but I can’t help but worry and have lost my excitement. This is my third and I am 35. I had no issues with the screening with my first 2. Now I wait for an appointment with a genetic counsellor. Anyone else experience something like this? Thanks.
